I had dual boot set up with my previous Ubuntu installation which allowed me either to use Windows XP or Ubuntu. This worked successfully.  I have upgraded to Ubuntu 14.4. The new Gnu Grub menu does not show my Windows XP installation on the start-up menu.

I need to resize root as there is not enough space left in the partition. At present I am not able to install new package nor update ubuntu. I tried sudo apt-get clean and emptying trash but it does not make significant space.  I have dual boot system (windows-7 and Ubuntu 14.04 LTS) with two Internal hard drive. Where Windows is installed in /dev/sda and Ubuntu is installed in  /dev/sdb. I tried to resize root using Gparted but it does not allow.

I recently installed Ubuntu in dual boot along with Windows 10 on an HP laptop. Initially I was unable to boot up Windows using grub as selecting the Windows options would just loop back to grub.  Then I performed a boot repair, and all these extra options showed up in the grub menu.  I'm able to open up Windows using "Windows UEFI bootmgfw.efi" option, but not using the standard option of "Windows Boot Manager (on /dev/sda1).  How do I reduce these entries and why can't I boot Windows using the latter option?  Here's an image of grub. The first option is Ubuntu:

I recently installed an SSD into my machine. The machine itself is a Lenovo thinkpad W520, and it previously had an internal HDD. I moved the internal HDD into an expansion bay (replacing the CD-ROM), and put the new SSD into the internal bay.   The problem I'm having is that I have my Ubuntu configuration EXACTLY the way I want it - I originally spent many hours configuring it to get it to the way it is now. I'd rather not do this again. But, I'd also like the boot-up gains I would get from the OS being on the SSD.  So, what I'd like to do is clone my Ubuntu partition onto the SSD. The catch is that the standard HDD is significantly bigger than the SSD. And it has a windows partition that I don't need on the SSD (I never use Windows, so if it boots off of the other hard drive, that's fine). The layout of my hard drives are as follows:  /dev/sda (SSD):     Model: ATA M4-CT256M4SSD2 (scsi)     Disk /dev/sda: 256GB     Sector size (logical/physical): 512B/512B     Partition Table: msdos  Number  Start   End    Size   Type     File system  Flags  1      1049kB  147GB  147GB  primary  ext4         boot   /dev/sdb (HDD): Model: ATA ST9500420AS (scsi) Disk /dev/sdb: 500GB Sector size (logical/physical): 512B/512B Partition Table: msdos  Number  Start   End     Size    Type      File system     Flags  1      1049kB  1259MB  1258MB  primary   ntfs            boot  2      1259MB  269GB   268GB   primary   ntfs  4      269GB   483GB   214GB   extended  5      269GB   416GB   147GB   logical   ext4  7      416GB   475GB   58.9GB  logical   linux-swap(v1)  6      475GB   483GB   8470MB  logical  3      483GB   500GB   16.8GB  primary   ntfs   What I've tried so far:  1) Resizing the partitions /dev/sdb5 and /dev/sda1 to be the same size. 2) Booting into Ubuntu 11.04 (from /dev/sdb5) and running dd if=/dev/sdb5 of=/dev/sda1 (of course this causes problems with booting, so I had to reinstall grub.. I can get it to boot, but then I have problems with initrd not finding some files ... presumably it can't load some partitions I think).  Now, I think those two steps are the wrong approach, because it will clone /dev/sdb5 EXACTLY - including references in fstab which point to the wrong hard drive. I'm not sure exactly how to rectify this. I could install Ubuntu 11.04 onto the SSD, then try and copy over all of my configurations, but I'm concerned that I'm going to lose something, or that I'm going to overwrite something like fstab that points back to the original hard drive.   Note that currently, I can still boot from the HDD, so it's not imperative that I get this figured out right away, but I do want it to be exactly how it is right now, so that I can maintain my current level of productivity (it's a work laptop).  Suggestions on how I might be able to overcome this difficulty?   Thanks in advance!

I'm tring to install Ubuntu 13.04 on my PC desktop but when i restart my PC, it always starts Windows 7, without asking me which OS would i like to run. I've got 3 HDD on my PC:     1: 200 GB with Win7   2: 500 GB partitioned with 4 GB of Swap, 150 GB of /home and the others GB of root (/)   3: 2 TB of various data.

I installed Ubuntu yesterday alongside Windows 7 and whenever I start my computer I don't have the option to boot Windows. When the computer starts it goes straight to Ubuntu without giving me an OS selection menu. When it goes to Ubuntu it gives me Ubuntu repair options and Ubuntu normal start option. I still have all of the Windows 7 files on my hard drive, but Windows 7 has no way to boot.

I've posted a question  that I have a 32bits windows 7 on a dual boot machine with ubuntu 10.04 upgraded to 11.04. From the responses I had from the questions, I decided to reinstall the windows 7 but this time a 64bits version.  I've install the grub on the first section of the HDD on which ubuntu is install, meaning the 2nd Drive.  I still want guidance before I proceed.  What would you suggest me as best way to achieve that without disturbing the boot loading.  thank you for reading this.

I have two separate SSD's. One of them has Windows 10 Pro installed, and the other has Ubuntu 14.04.3 LTS.   When my computer boots I get no grub menu to choose the operating system I want to boot into, it directly boots into Ubuntu automatically. I can boot into windows with on problems when setting its SSD as the first one in the boot sequence in the BIOS.  I have a third 2TB HDD that I use only for storage.

It's my first time installing ubuntu. I have Windows 7 and 8 before in my laptop (Acer Aspire 4752z). After Ubuntu (12.04) installed in my laptop, the Windows boot loader didn't recognize my Ubuntu so I updated grub from a live USB.   And after grub updated, Ubuntu was booting perfectly but my Windows wasn't listed in the grub menu. So I follow someone instruction to update grub again. And after reboot, the grub menu didn't show anymore.   After searching about this problem on the net and trying to update grub again and again, I decided to delete the Ubuntu partition from live USB. And shortly after, I booted to Windows with Hiren boot and I used mbrfix. But i think it failed. Now i cant show my BIOS setup or boot from DVD or USB.   After that, the only screen i can see after booting is:  error: unknown filesystem grub rescue&gt;

I had installed Ubuntu inside Windows XP but then I formatted XP and installed Windows 7.   EDIT1: I used Wubi for the same. I want to know which one of the two will solve my problem? creating a virtual disk or resizing root? Also is resizing root possible as the 4GB ext4 partition is already in a NTFS format Hard Drive partition.  At the time of installation I had allocated only 4GB of space to Ubuntu. I want to increase that size as I keep getting a low disk space notification.   I have surfed through a lot of similar questions but this is not a duplicate.  Because I want to know a little about the file systems. In order to solve my problem,do I have to increase the size of root.disk? Or will it be solved by creating a virtual disk?  Also I want to know the difference between creating a virtual disk and just increasing disk space of root.I'm new to Ubuntu so I don't know how the file systems function.  EDIT2:I have created a virtual disk of 10gb ,but I'm still getting the same notification.Is there anyway to install all further applications on the virtual disk I created?

I installed Ubuntu alongside Windows 8, however have decided to unisntall Ubuntu.  First I booted into Parted Magic and, using GParted deleted all the ext4 and swap partitions.  This leaves me with the same partitions I had before I installed Ubuntu:  /dev/sda1 ntfs WINRE_DRV /dev/sda2 fat32 SYSTEM_DRV (my UEFI partition) /dev/sda3 fat32 LRS_ESP /dev/sda4 unknown Microsoft Reserved Partition /dev/sda5 ntfs Windows8_OS /dev/sda6 ntfs LENOVO /dev/sda7 ntfs PBR_DRV   I expected deleting the partitions would be enough to remove Ubuntu and allow me to boot back into Windows 8, however whenever I boot I get the following error:  error: no such partition.   which is followed by GRUB rescue:  grub rescue&gt;   In my UEFI partition, there are two directories BOOT and EFI. In BOOT is a single file - boot.sdi. In the EFI directory are another two directories, BOOT and Microsoft. Inside BOOT are two files, bkpbootx64.efi and bootx64.efi. The Microsoft directory has a directory in it named Boot. Inside it are the normal Microsoft EFI files (as far as I can tell).  Thinking there were still GRUB files left, I ran find . -iname "*grb*" and find . -iname "*grub*" in the UEFI partition, however only found one empty file, bootx64.efi.grb (which I deleted).  How is GRUB still installed, and how can I uninstall it?  I'm pretty new to UEFI and so things may need explained in detail. The computer is a Lenovo IdeaPad Z580.  edit: I forgot to mention, I deleted the ubuntu folder in the UEFI partition.  edit 2: I managed to get back into Windows through a "System Recovery" option in the laptop's BIOS settings. This may or may not have solved the issue.  edit 3: okay, I can boot almost normally now. When I boot, I see No partition active for a couple of seconds then Windows boots. How can I remove that?

After having installed the 64bit version of Ubuntu 12.04 on my Lenovo B570 I ran into the same problems I had when installing 11.10 with Grub not playing nicely with a uEFI system. I used the same technique as last time to solve the problem (using a Super Grub Disc LiveCD session to repair Grub) and my system happily dual boots between Ubuntu and Windows 7  However now when I boot up the Grub menu only displays   Ubuntu, with Linux 3.2.0-24-generic Ubuntu, with Linux 3.2.0-24-generic (recovery mode) Previous Linux versions Windows 7 (loader) (on /dev/sda1) Windows Recovery Environment (loader) (on /dev/sda4)   I no longer see the option to use Memtest86+ which was there previously, having checked in the Ubuntu Software Center I can see that the package is installed, but how to I make the option to run it once again appear in the Grub menu?  I've tried:  sudo update-grub    which doesn't make any difference.  sudo chmod +x /etc/grub.d/20_memtest86+    results in:   chmod: cannot access /etc/grub.d/20_memtest86+': No such file or directory   and entering  ls /etc/grub.d/   results in:  00_header        10_linux      30_os-prober  41_custom 05_debian_theme  20_linux_xen  40_custom     README

I have dual booted Windows 7 &amp; Ubuntu 14.04 with EasyBCD, i.e. I have installed grub on the Ubuntu root partition &amp; added entry of linux to Windows bootloader using EasyBCD. So effectively i am using Windows Bootloader to boot into either of them. Working perfectly.  As i already had 4 primary partition on HDD, i converted one of  that (NTFS-Windows 500 GB) to Logical using EaseUs Partition, so that around 70GB of uncollected space on HDD could be used.  NOTE: Before that the 500 GB partition was Primary &amp; i was able to see all partition in Gparted. "What i mean to say is all was working properly".  The problem (i.e. after conv. of primary to logical) is i am getting this message after starting Gparted &amp; shows entire partition as Unallocated.  Unable to satisfy all the constraints on the partition  $ sudo fdisk -l  Disk /dev/sda: 1000.2 GB, 1000204886016 bytes  255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors  Units = sectors of 1 * 512 = 512 bytes  Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0xe6bfc2a4     Device Boot       Start         End      Blocks   Id  System   /dev/sda1   *        2048      206847      102400    7  HPFS/NTFS/exFAT   /dev/sda2          206848   427624447   213708800    7  HPFS/NTFS/exFAT   /dev/sda3       427624449  1805438975   688907263+   f  W95 Ext'd (LBA)   Partition 3 does not start on physical sector boundary.   /dev/sda5       427624512  1532823551   552599520    7  HPFS/NTFS/exFAT   /dev/sda6      1532825600  1780301823   123738112   83  Linux   /dev/sda7      1780301824  1805438975    12568576   82  Linux swap / Solaris   So what is the cause of this problem.  I know there might be duplicate for this at "" (that was bug probably &amp; was for old version of Ubuntu 13.04) &amp; ""  Also, if there is any chance that both errors are related or complementary to each other?  So, is this problem caused because of Sector Size (512 bytes/4096 bytes) or my mistake of converting a Primary partition to logical using EaseUs rather than some of the Ubuntu Tools. How can i rectify this?  If any further info needed, feel free to ask.  UPDATE  @psusi, sudo parted -l says same as what gparted said. (Unable to satisfy..) @oldfred, i have started chkdsk, will update you with the same.  (Thanks to both)  @rod smith, I will try your suggestion after i done with chkdsk.Thanks !

after upgrading to 19.04 the Grub menu have become hidden. It still works and I can boot to both Windows 10 and Ubuntu by blindly finding the entry and pressing enter. I have tried to edit the /etc/default/grub and running sudo update-grub afterward but no change. Here is how it looks now:  # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: #   info -f grub -n 'Simple configuration'  GRUB_DEFAULT=0 GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2&gt; /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" GRUB_TIMEOUT_STYLE=menu GRUB_HIDDEN_TIMEOUT_QUIET=false  # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"  # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console  # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480  # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true  # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true"  # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1"   I can't use either Shift or Esc to make it visible too. After pressing either of these, Grub doesn't work anymore and I need to turn my laptop off and on in order to boot.  Edit: Not sure if it helps or not, but I just realized that if I go to the BIOS when I exit BIOS the grub menu shows up with no problem. The next time I boot, the grub menu is invisible again.

I am dual booting Windows 10 and Ubuntu 18.04. How to tell grub not to show the boot menu and boot directly to Windows 10 by default? What should I do if I want to boot to Ubuntu 18.04 instead of the default Windows 10?
