I was recently moving a few partitions between drives to fix some organizational issues that have risen up as I've purchased new disks.
Originally, I had /dev/sda with:
/dev/sda1/ - ntfs - Windows Recovery /dev/sda2/ - fat32 - EFI /dev/sda3/ - ntfs - ** This is where windows was installed ** /dev/sda4/ - ext4 - ** This is where arch linux was installed **
/dev/sda3 (the windows partition) to a new disk and resized /dev/sda4 (arch linux) to use the unallocated space. This was all done through a gparted live usb, booted in UEFI mode.
I then booted into an Arch installation USB (also in UEFI mode),
arch-chroot'ed, updated everything in my fstab and confirmed that the fstab entries worked by mounting everything with
After that, I made sure os-prober was installed and ran grub-mkconfig, which reports that windows boot manager is found on
/dev/sda2, which is my EFI partition.
The problem is that when I try to boot, windows errors out, tries to repair startup and gives up. It seems like the windows boot manager doesn't know that everything has been moved to
Is there anything I can do to fix this? How can I configure the windows boot manager to boot from the new location?
Edit: For transparency, I'll include that I also asked this question on superuser, found here
