Hello I have a Dualboot system with Windows 10 and Ubuntu 20.04 and I use Ubuntu grub so the grub is like this:-                                         Grub [Its version] 1) Ubuntu 2) Advanced option for Ubuntu  3) Windows boot loader 4) UEFI Configuration  So I want to change it to this :- is it possible?                                             Grub [Its Version] 1) Windows Boot Loader 2) Ubuntu  3) Advanced option for Ubuntu 4) UEFI Configuration  And also after updates the grub is updated everytime so will it revert it to the previous even if I changed it? Thankyou.

I have both Windows 7 and Ubuntu installed on a shared machine. Because a lot of the non-developers use Windows, I'd like to change the boot order to make it easier for them.  Currently the boot order looks like the following:   Ubuntu 11.10 kernelgeneric *86 Ubuntu 11.10 kernelgeneric *86 (safe boot)  Memory test Memory test Windows 7 on /dev/sda6   How do I change the default order so that Windows 7 is at the top of the list?   Windows 7 on /dev/sda6 Ubuntu 11.10 kernelgeneric *86 Ubuntu 11.10 kernelgeneric *86 (safe boot)  Memory test Memory test

I went ahead and installed windows 10 on my windows 8 and Ubuntu dual boot PC. All went smooth and Windows 10 works perfectly however the computer automatically boots to Windows and the grub launcher is missing. The partitions are still there I just need some help getting Ubuntu back. Thank you in advance!   Edit: I found a way around it. I don't know of this works for everyone but I went in to the control panel and went to update and recovery. Then I went to recovery and booted into uefi.  Then I selected boot from device and my Ubuntu partition was there and I could boot into it.  Feel free to post other solutions though!

Are there any drawbacks to installing Ubuntu 13.10 (and soon 14.04) in Legacy BIOS instead of UEFI?  I have installed 13.10 64bit in Legacy by mistake and was just wondering if it would hurt anything to simply leave it there as is?  EDIT  Everything seems to be running just fine in Legacy and all my drivers work.

I've tried several approaches and it still boots directly to Windows 10. It is a Toshiba  with Windows 10 the original OS.  I read and tried to follow all prerequisite steps in , and first tried Ubuntu 14.14 LTS, which installed but showed no dual boot menu.  Various answers and sources  have suggested I could then tell the UEFI to start with Grub 2, but I see no such option. This Toshiba's UEFI config menu has never shown anything but the hard drive and USB as boot sequence options. The only other relevant setting seems to be Safe Boot on/off, which has never seemed to have any effect on behavior at any point in the hours and hours (and more hours) of trying things I have done. There is no "boot mode" option  - I suppose it is UEFI-only (no legacy option)?  The info-packed answerer said 15.04 has always just worked for him, so although I would prefer LTS, I tried Ubuntu 15.04, telling it to replace the 14.14 installation, and it is installed, but is equally unbootable.  I saw the suggestion that Toshiba may be violating the UEFI standard and annoyingly testing for "windows" in the file name and that I could rename the Linux bootloader to windows... but I don't know how to access the EFI partition - I assume I'd need to know how to find and mount it in Linux? I didn't see complete enough directions for my familiarity level, so I didn't try that.  Following advice on , I tried using a EasyBCD and managed to wipe my BCD making Windows 10 unbootable .  The most recent thing I've tried is , which I ran in all its steps but it had no visible effect. Its docs say the final steps should be to show its output data to my favorite help source, so here I am, and .  Any suggestions?

I have dual boot configured with Windows 7 (32bit) and Ubuntu 12.04(64bit). I installed Ubuntu after windows, now my windows is corrupt due to some virus and I need to reinstall it. Currently when I start my PC, grub loader comes up and I need to select Ubuntu or Windows.   I was wondering how can I install windows again and still have my Ubuntu install? Is there a way to do this?  I do not want to install Ubuntu again and lose my settings and data there.   Thanks, Ketan

Today I installed Windows 8.1 and it broke my GRUB. I tried to run the boot-repair GUI on a live session of Ubuntu but after the restart of the PC GRUB displays ONLY Ubuntu.   Before the installation I had on the first HD Ubuntu installed alongside with Windows 7 and the grub displayed both of them without problem.  After I installed Windows 8.1 on the second HD the boot loader(?) was replaced with the Windows one and I could select only between Windows 7 and 8 to boot, but not Ubuntu.  How can I fix GRUB now? I wish GRUB could displays all the three OSs (even if different HDs). If not possible I wish I could just choose which HD to boot and then the grub to displays correctly the OS of that HD.  This is the  (broken link).

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 installed Ubuntu in the dual-boot configuration so that I can still boot up in Windows. But I just want to get Windows off of the machine.  Anyone know how to do this without having to go through another Ubuntu install? Also are all of the Ubuntu updates safe to take? Does Ubuntu have restore points in case something goes haywire from the updates?

I installed Manjaro as my first distro and everything went pretty smoothly up until grub. When I select Windows 10 in the grub menu instead of Linux, windows takes a lot longer than usual to boot. Once booted, it seems fine - until the next boot where grub is completely skipped and windows is loaded into automatically.  The only way I have found to get grub back, is to enter my UEFI settings and rearrange the boot order so that Manjaro is on top. As soon as windows boots, this is rearranged so that Manjaro is down at the bottom of the list.  To sum up:   Grub works fine until windows is loaded, at which point it isn't used anymore To restore grub I must rearrange the UEFI boot order. This works until the next windows boot This problem doesn't occur with Linux, I can boot it many times over with no problems at all.   How can I prevent Windows 10 reordering the boot order in the UEFI so that grub is used all the time?

Ok, so I'm such a newbie to Ubuntu and I bought a Windows 8 pre-installed laptop last month.  I updated to Windows 8.1 and then I thought about installing Ubuntu as a dual boot so I could mess around and learn more about it.   So I followed a Youtube tutorial (  ) and I got my stuff working fine.   The first few times I booted I got the GRUB menu instead of my default HP Boot OS Manager, and I was able to select my OS.   So I went to sleep and the next day I turned on my computer and the GRUB menu did not show up. I tried several times and it didn't automatically show up.  In order for me to see the GRUB menu I had to turn on my PC and on start had to press ESC to pause startup and press F9 to get boot options. Then from there I had to pick from OS Boot, Ubuntu, Ubuntu (Yes there were two Ubuntus available) and a default EFI file thingy.   When I click the first Ubuntu I get the GRUB Menu (I was too scared to try the second in case I screwed my laptop up) and I can safely load Ubuntu from there and use it (although I do have to increase my brightness every time I load Ubuntu because it somehow reduces my brightness to complete darkness on boot)  So my problem here is why isn't my GRUB showing on boot, after it worked on the first day?   My laptop is a HP TouchSmart j-078CA.  EDIT 1: FYI I just switched to Ubuntu LiveCD to check my Installation and found out that one of my partition is flagged as msftres. Here is a screenshot of my GParted on a LiveCD:

Can you guys please help me use Grub Customizer to set an older version of the kernel 4.4.0 of Ubuntu 16.04 LTS as default when booting? I'm not using a dual boot system, and I have installed 4.4.8 kernel to help me solve the suspend problem, but it's draining my battery.  What do I have to do, I wouldn't want to f*** things up.

I have dual booted Windows 10 and Ubuntu 16.04 in UEFI mode (secure boot off). My time in BIOS is correct.  When I boot into Ubuntu and then boot into Windows 10, it shows the wrong time. I have to correct it manually or by the internet in Windows 10, and when I reboot into Windows 10 then it is not a problem. The clock will show the correct time. And then when I reboot to Linux the clock is correct, but switching back to Windows 10 the clock messes up again.

Each time I've tried to dual boot Ubuntu with Windows I always have difficulty with the same thing... editing the default option on the grub boot loader. I'm now running 11.10 and have run into the same problem.   Startup-manager didn't work on 11.04, neither does it work on 11.10. Editing GRUB_DEFAULT= in the /etc/default/grub file doesn't seem to work either.   This shouldn't be difficult, and I'm sure there's a simple explanation. Could someone please tell me what it is?

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 have a PC with 5 hard drives (SSD and HDD). One of the drives has Windows 10. In the past, I have tried to install Ubuntu and Windows using the following method so there will be no interference between the two operating systems:  I Simply removed all the hard drives, except the one that I wanted to install Ubuntu, then install ubuntu and connect other hard drives. Then select the boot drive using the BIOS.  Can I do the same thing without taking out taking all the drives?  I mean I do not like  to see the GRUB on boot, I want windows to boot as default without the need for GRUB.
