[Boot-Repair] Graphical tool to repair the PC boot in one click

That procedure works for many, but is really for those systems that have modified UEFI to only boot Windows. If you were able to boot Ubuntu entry from UEFI before, I do not understand why you could not now.
You many have to rerun renaming after Windows updates that replace the renamed files with new Windows files.

Hi @OldFred

I have a problem with loading Windows 7 before, it was solved by marking the dev3 as boot with gpart.

I have dual boot windows 7 and ubuntu 13.10. I have a problem with loading Windows 7 before, as it showing Windows logo, the display became flickering and then hung or restarted. It was solved by marking the SDA3 (Windows partition, drive C as boot with gparted. All works well.
A few days ago, i installed ubuntu 14.04 (fresh install, format old ubuntu 13.10 partitions, still dual boot with windows 7). I can load both OS without problems till now. I cannot load the Windows 7 again, with the same problem as before (flickering display when showing Windows 7 logo and then restarted), i see SDA3 is marked as boot. Tried to re-mark but still not working. Please help!

Your actual Windows boot partition is sda1. Boot-Repair copies boot files to main partition or c: drive as so many users have never seen the hidden boot partition and just delete it. Then they do not have any boot files. But sda1 also has recovery files which are Windows repair files. Boot flag is only used by Windows if you restore Windows boot loader, grub will use either sda1 or sda3 to boot if boot files are in those partitions which for you they are.

Did you make a Windows repair CD or Flash drive? If not you should. Grub really only boots working Windows and Boot-Repair can only make very minor fixes to Windows.

Other suggestions here.
See also this user who did get f8 to work. You would have to try to boot from sda1 for f8 to work.

Usually changing the shim or grub to be Windows efi file works. You used grub, try copying shim.

You will not get grub menu, but then if issue after menu normally it should just hang. With BIOS it was always hold shift key from BIOS until grub menu appears. With UEFI sometimes it is escape.

Otherwise I am down to just installing in BIOS boot mode. You can adda 1 or 2MB unformatted partition anywhere on drive and with gparted give it the bios_grub flag. Then use Boot-Repair to uninstall grub-efi and install grub-pc. Purge & reinstall without efi checked I think.

Hi oldfred,

I've been busy these last days, but I finally solved my problem. It turned out that in addition to the buggy bios I had a problem with the EFI partition. What solved it was to format it and then replace the windows efi file with the efi file generated by boot-repair.

Thank you for your help in this matter.

Hi all, my first dual boot attempt with Windows 8 and Ubuntu14. Installed ubuntu successfully, just can't boot into it. Played around with it quite a bit, Secure Boot is off. Here's my paste ..

Any help appreciated, I'm pretty much learning how to do this from scratch at this point so forgive me if I muddle at your responses.

[oldfred]

Make sure secure boot is off.
It looks like you installed in BIOS boot mode, but Boot-Repair converted to UEFI boot as now you have ubuntu as an UEFI boot option. Can you select that option?

BootOrder: 0003,0001,0000,0002

Boot0000* Windows Boot Manager
Boot0001* UEFI: KingstonDataTraveler 2.0PMAP
Boot0002* Hard Drive
Boot0003* ubuntu,BootCurrent: 0001

What computer is this and what model?
Some vendors modify UEFI to only boot Windows.

Hi all,

I installed Ubuntu 14.04 on my notebook. Windows 8 was already installed and i like to have a dual-boot system. I cant start Windows 8. I have an GRUB entry "Windows Boot Manager (on /dev/sda2)" but if i chose it I return to GRUB immediately. Ubuntu starts without any problem. I have run Boot-Repair and here is the paste: http://paste2.org/yOxAJ3G4 but the issue still exists.

It would be nice if anybody can give a hint to solve the problem.

This is from the 'buggy' UEFI rename that Boot-Repair does:
/EFI/Microsoft/Boot/bkpbootmgfw.efi

What computer & model. Some only boot Windows, so the rename is one of the ways to get those system to actually boot grub.

Always say no until proven that you only can boot Windows entry from UEFI menu.
buggy-kernel detected. Do you want to activate [Backup and rename Windows EFI files]? yes (if any choice fails, please retry with the other)
To undo & to rename files to their original names, you just need to tick the "Restore EFI backups" option of Boot-Repair.

But if you left Windows hibernated (fast boot) then it will not boot from grub. Or if secure boot is on.

Undo the rename, and see if you can directly boot Windows from UEFI menu.
Then see if you have and can boot the ubuntu entry in UEFI menu. You have ubuntu in UEFI, but some vendors hide it or will not let you use it.

 BootOrder: 0001,0000,000B,000C
Boot0000 Windows Boot Manager
Boot000B UEFI: IP4 Realtek PCIe GBE Family Controller
Boot000C UEFI: IP6 Realtek PCIe GBE Family Controller
Boot0001* ubuntu.

There are several other work arounds:
Systems that only boot Windows from UEFI. Often Sony & HP, maybe others

some find this changing this to be shim or grub /EFI/Boot/bootx64.efi
Then booting device or hard drive works also.

Any rename either manually or with Boot-Repair will need to be redone after a Windows update as it will restore Windows files.

Alternative to Boot-Repairs rename of shim.
Some systems work better to register grub/shim from inside Windows - for those that keep resetting Windows as default

Some install rEFInd which seems to be another workaround and has nice boot icons.
