But when starting into grub and trying to start windows from there I still get the same error message. Here is another boot report as analyzed by boot-repair. As you can see on line But this entry uses a backup of the EFI to boot into windows. GRUB instead uses a more recent file to try to boot windows as you can see here in the grub. Could it break anything? And why does only the backed up version works and not the recent one? My whole boot setup looks a little messed to me.
The efi file was there when i browsed to the location using file explorer its just that during booting it was not being found. Used balenaEtcher this is the only rufus alternative i found for ubuntu to create a bootable windows 10 media.
Used balena etcher to etch the windows 10 iso file onto this usb it gave a warning regarding the iso that it might not get recognised ignore it i did. Now once u have a bootable windows 10 usb, restart the pc and when u are in the grub boot menu press c to enter the command line.
My usb was hd0 yours may appear different but u can find it by first doing the "ls" part without having the usb inserted then again with the usb inserted or like in the next step. Do not have a craving to keep hitting next, or you will end up installing Windows.
It will boot your computer into Advanced Recovery. Select Troubleshoot. Under Advanced options screen, you will see Startup Repair.
Click on it and follow the instructions. I'm not sure whats the exact way to solve this problem. But I tried a few thing and finally came up with a solution! So at least a small summarize:. And when trying to boot from a USB stick I also got stuck with a blank screen. This solved the problems with mouse, keyboard and USB stick! I changed just this one single line, nothing else!
This made it working for me! Yes it looks a lot like Rescatux is responsible for this but I don't know exactly what I did that rescatux created this backup file.
Seems like each answer has a completely different experience with resolving this issue. I removed them all, disk was not full anymore and I could boot Windows again without further issues.
Here's a much simpler alternative. As the root user, list all the partitions on your hard drive replace sda with the device corresponding to the appropriate hard drive :. See the instructions for the emergency boot device above as a reference.
Now, as the root user, create the mount point for the ESP, and mount it replace sda1 with the device node corresponding to the ESP :. As the root user, mount it if it's not already mounted:. If the system is booted with UEFI and systemd, efivarfs will be mounted automatically. However in the LFS chroot environment it still needs to be mounted manually. In this case you should boot the system in UEFI mode with the emergency boot disk created as above.
Another workaround is to boot from TrueCrypt as the main boot loader and then hit the Esc to chainload the following partition if one exists or the following disk. However, if Windows is on the same disk on a different partition, or if regular chainloading doesn't work, then read on. For instance, to boot Windows 7, add the following to the grub. Filesystem UUIDs can be obtained with blkid. Remapping the devices to set the primary boot disk to other disks can be achieved by using the drivemap option like so:.
Note that it only supports booting on MBR disks. Yes, unfortunately i found the case as you said. Is there a way to trick bootmgr that it runs on mbr partition? Grub2 is a powerful boot loader and supports booting most operating systems.
This article will guide you to boot Windows from Grub2 command line. This is the Grub2 screen that stops in rescue mode. Entering rescue mode Unknown command 'search'. Unknown command 'chainloader'.
