TestDisk is a program running in console, but with this tutorial, this program seem more accessible to you.

USE WINDOWS 10 DISK TO REPAIR OR CREATE BOOT PARTITION ZIP FILE

To resolve this issue, download 'TestDisk', unzip the downloaded zip file and run the 'testdisk_win.exe' file. Which means 'raw data' because it no longer recognizes files of that partition system. This should switch the computer to use rEFInd by default, and you should be able to boot everything normally.When the hard disk is faulty or for other reasons, it happens that partition is no longer accessible.ДЄlso, if you go to the start menu -> Right click on Computer -> Manage, you will see that Windows displays the data partition as RAW.

If you can boot both Windows and Linux, install the Debian package of rEFInd in Linux. This should give you an option for Windows and at least one option for Linux. Instead of restoring GRUB, you could consider installing rEFInd to your hard disk, too.Д®DIT: Try using my rEFInd boot manager: Use the USB flash drive or CD-R image to create a suitable medium and boot from that. This question and answers cover the issue from a different angle. Briefly, you must use the -o option to efibootmgr to set GRUB's entry as the first one. Once Linux is up and running, you should be able to use efibootmgr to restore GRUB as the default boot loader, but the details depend on how it's configured now. Alternatively, you should be able to use a CD-R or USB flash drive version of my rEFInd boot manager to get Linux booted.

Third, if you can figure out how to boot your live CD in EFI mode, Boot Repair should fix the problem. Thus, you may need to experiment to figure this out. You can usually do this via a boot manager that's accessed by hitting Esc or a function key early in the boot process (before GRUB appears) but there's no standardization on how to access this boot manager or what options it provides. You need to learn how to control your computer's boot mode. Second, you had this problem because you booted your emergency disc in BIOS/CSM/legacy mode rather than in EFI mode. Only once you're sure that you can mount the partition and use it normally should you proceed.

If the partition has errors, fix them or restore your system from a backup.

Test your Linux root ( /) partition with fsck (or equivalent functionality in GParted or other GUI tools).

Remove the bios_grub flag from your Linux root ( /) partition.

Thus, before you do anything else, I recommend you: Most importantly, if Boot Repair re-ran the GRUB installer after you set the bios_grub flag on your Linux root ( /) partition, you may have trashed that partition.

It's normally about 1MiB in size, although it can be smaller in some cases.

GRUB 2 uses this partition to hold part of its boot code when the computer boots in BIOS mode. I re-installed grub: grub-install /dev/sdaДЇirst, the bios_grub flag in parted or GParted is a way to identify a BIOS Boot Partition. I logged on the system with chroot: sudo chroot /mnt I mounted my Ubuntu system disk: sudo mount /dev/sda9 /mntДЄnd the other things: sudo mount -bind /dev /mnt/dev But it's empty (the only voice is 'System Setup'). When I boot my PC with SecureBoot OFF, I can reach the GRUB menu. My boot is on UEFI mode, Secure Boot is 'off'.

So I tried again with Boot-Repair but it always gives me the 'GPT detected' error. Then I used fsck and it didn't find any error. My Grub was working fine (using UEFI) before I updated Windows. So I tried to set my sda9 (I think that it's the Ubuntu system partition, since it's ext4) with the bios_grub flag and then to run Boot-Repair again. Alternatively, you can retry after activating the option. This can be performed via tools such as Gparted. Please create a BIOS-Boot partition (>1MB, unformatted filesystem, bios_grub flag). If I click on Reccomended repair I get this error: I ran Ubuntu using Live USB, I used Boot-Repair but something went wrong. Since I updated Windows to 8.1 my Grub menu disappeared.
