I'm new to linux world. Just  downloaded ubuntu and installed it alongside with windows 7  . In grub when I choose ubuntu, it opens with no problem, but when I try to open windows 7, this message appears:   A Disk Read Error Occured. Press CTRL+ALT+DEL to restart.   I googled for that  problem which  directed me to download a boot repair tool,  when I choose : advanced options / retore MBR --&gt; apply, then restart computer , It boot to win 7 without loading the grub menu.  then I opened the live ubuntu from a  USB,  launched the "boot repair" again, choose : recommended repair , then restart, It  returns to the first  problem , grub menu appear, from which I can choose only ubuntu , but win 7 show this msg again :   A Disk Read Error Occured. Press CTRL+ALT+DEL to restart.   I repeated more and more with the same results ...   What should I do?  I created a boot info summary using the "boot repair tool" if this can help , it's in .

I want to install Ubuntu and learn Linux.  I've been using Raspbian a bit and really would like to get away from Windows as much as possible.  The only problem is some of the games I use requires Windows for now.  Also, I'm taking classes through Coursera and using online tutorials to learn Linux from and would like an operating system installed besides the Raspbian I have on my Pi.  I have a desktop computer with Windows 10 installed on a SSD (M.2 if it matters) and another HDD used to store files. I have a new 1 TB HDD I'd like to install Ubuntu on. My plan is to install it and place the GRUB bootloader on the new drive.  I can then point the UEFI to that drive as the primary boot drive and GRUB should allow me to choose Linux or Windows. My thought is if I do this, I can change the boot order in UEFI back to C:\ drive and have the machine boot directly to Windows as it does now. Then I have the option of having a dual boot system or a Windows only system. Is this viable?  Should I use the whole drive for Linux?    Also, I'm reading a couple different opinions on disabling Secure Boot and Fast Boot from the UEFI.  Any reason not to disable these in my plan above?  Any other advice is welcome. I appreciate the help!

I need to install Ubuntu instead of Windows 7. Can you tell me the steps to do it? I don't want to install Ubuntu alongside Windows. Any precautions needed before installing Ubuntu? How do I install Ubuntu 11.10 without losing the current data in my laptop?

After I ran Windows 10 update this afternoon my partition table broke... I had dual boot with Windows 10 and Ubuntu 14 with Grub as the boot loader. The error that came up was "Error no such partition, Entering rescue mode... grub rescue>". I googled it,  about the boot-repair ISO, installed it on a USB, ran the repair, got this report, but still no luck:    Now the boot skips Grub entirely and goes to Windows boot manager which fails with "The boot configuration data for your PC is missing or contains errors". So now instead of dual boot I have zero boot. Thanks Microsoft.  Anyway can you guys help me interpret the disk info in the pastebin link? I don't remember my partition configuration but I believe Ubunut had slightlty less disk space than Windows. Questions I have:   Is the Ubuntu partition still there? Could it be the one named "Extended"? (sda4) Where would GRUB be? Gone? Can it be reinstalled? how?   I don't really care about the Windows partition anymore, but it would be nice to rescue Ubuntu.

I sent this to boot.repair@gmail.com, still no response thought I could get a faster solution here.  I am running Windows 7 64-bit and Ubuntu 12.04 LTS on separate partitions.  The message is sent is:  Boot-Repair URL:    Originally I was unable to access Ubuntu after a windows update (Ubuntu was installed using wubi). Rather than logging into Ubuntu from the Windows 7 Bootloader, it lead to the grub> command prompt.  No matter what I did here, it would not log me into linux.  As a result I uninstalled Ubuntu from the Add/Remove Programs application in Windows 7.  I then re-installed Ubuntu 12.04 LTS using a liveCD-USB.  This time however, I created a partition.  I then restarted and got the GRUB bootloader which loads Ubuntu 12.04 LTS with no problems, however when I select windows (listed as "Windows 7 (loader)"), it just refreshes the grub bootloader instead of loading Windows 7.  I then used the Windows 7 repair disk to run bootrec/fixmbr and bootrec/fixboot.  This led to no bootloader coming up when I started my computer.  Instead I got a blank black screen with a flashing white cursor.  I went on to do a bootrec/buildbcd and bootrec/scanos.  These did nothing to change the situation.  When I ran bootrec/scanos it said that no Windows 7 installations were present.  After this I decided to reinstall WIndows 7 only for this to do nothing to change the situation.  Afterwards I did a boot-repair in which I began to get the GRUB bootloader, which would load ubuntu 12.04 LTS, but still would not load Windows 7.  I also did a sudo update-grub which recognized Windows 7 as being installed, but still didn't fix the issue of loading Windows 7.  While running Ubuntu I have no problem accessing my WIndows 7 partition which is formatted as NTFS.  It shows all the files and folders reflecting that the re-install did take place, and it also shows all of my old applications and folders in the Windows.old folder.  I am completely stuck at this point and have no clue what I should do next.  Any help you can offer me will be greatly appreciate.  Thank You  --gap

I am trying to install a fresh version of Ubuntu in my computer without touching the windows 10 dual boot! In the Installation Type, the first option seems exactly what i wanted to do.  My question is, is this feature is safe to use? because i don't want to lose any windows files and other NTFS partitions on the hard-disk. Please eliminate my confusion. Note as that i dont need any files or media which are in the ubuntu partition, Thanks.

I have a computer which is currently running Ubuntu 14.04. I would like to dual boot with Windows 8. I can not find any instructions for installing Windows after Ubuntu is already installed. I am only finding instructions for doing the opposite, Installing Ubuntu after Windows 8.

I have installed Ubuntu as dualboot with Windows 7. Now I'm no longer using Ubuntu so i removed the Ubuntu partition and added the unallocated space to my Windows 7 partition. But after I restart my computer it goes directly to the error:   error: unknown filesystem grub rescue &gt;   I don't have the original Windows CD to fix the MBR. Is there a way to fix this error without using the Windows CD?

I installed Windows 7, which ate Ubuntu's boot file. When starting up the computer, it now goes straight to Windows, without giving me the option of booting Ubuntu.   How can I get Ubuntu back?

I am dual-booting Windows 7 and Ubuntu, both installed on separate partitions. I don't need Ubuntu anymore. How can I remove the Ubuntu partition(s) and add the reclaimed space to my Windows 7 partition for saving files in Windows?

Okay, so here's the story.  I am trying to install Ubuntu 13.04.  I currently have a 2TB drive in my computer where Windows 7 boots from, and a secondary 500GB drive that also has a bootable installation of Windows 7, because the version on the 2TB is a clone of what was on the 500.. I do not need any information on the 500 as I already have it moved over to the 2TB.  What I want is to completely reformat the 500 so that it has about 300GB for NTFS and the rest for Ubuntu.  However, I can't seem to find a straightfoward way to do that in the Ubuntu installer.  If I click on "Install Ubuntu alongside them," it does not give me the option to select my 500GB drive, only my 2TB.  I do NOT want any linux partitions on my 2TB drive.  I do not want to click, "Erase disc and install Ubuntu" for obvious reasons.  Finally, clicking "something else" brings up a menu that is quite confusing.  I can kind of figure out how to use it, but it's not as straightfoward as I'd like..  Further, I know that Ubuntu requires a SWAP partition, but I do not know how much, or even how, to allocate that with the stupid dropdown menus it gives me.  So, to get to the point..  What is the easiest, safest way to do what I want to do?  That is, allocate approximately 200G for Ubuntu on my 500G drive, and be able to choose between Windows 7 on my 2TB drive and Ubuntu at startup - all, of coarse, without touching the 2TB drive at all.  Thanks!

I first had windwos 7, then I installed Ubuntu alongside and when my laptop starts I can choose between ubuntu and windows (the ubuntu boot screen) .  Now I have installed another ubuntu inside the windows 7 using virtual box. I want to remove that first ubuntu installation and free up its partiotion. Can I do it without making any problems for the windows and boot screen?

I'm new to how Ubuntu works and installed it yesterday alongside Windows 7, but in doing so I have created a few problems. I have partitions for Windows, Ubuntu, System Recovery, and storage for all my files with the intention to access them on either OS, but I don't even see all of my drives listed on Home Folder. Not to mention that  during the Ubuntu instillation I managed to screw up any chance of booting to the Windows side of things at all. I'll fix Windows once I get my hands on a copy in a couple days, but in the mean time any suggestions for accessing my files?  If you need me to find any data about my computer to help you figure out what's wrong with it, please don't hesitate to tell me what I need to show you. Thanks

I have extremely important stuff on my windows partition which during the ubuntu 10.10 installation,when it said that I should create something called swap space, I selected it to be a swap space (without even knowing what it actually meant)  The Grub2 doesn't show up so I don't get a choice to boot Ubuntu or Windows. I don't get my windows partition as a removable device in Ubuntu either. When I go to disk utility and select the sda2 (i.e.. my windows partition) and click edit partition and select HPFS/NTFS for the type and tick bootable and click OK the small processing sign keep on rotating on the bottom right of the sda2 in the chart and after about 10 to 15 minutes it gives an unknown error and thus, I am still unable to use my windows.  I am even worse than a beginner who doesn't know a thing about Ubuntu so please be patient and help me out.
