I'm searching for a way to chainload another bootable partition from my USB stick, where a windows10.iso contents is resided.
My partition layout in GPT looks like the following:
- bios_grub raw (for legacy boot)
- EFI Fat32 (UEFI directory)
- WIN Fat32 (windows 10 iso contents)
- BOOT Fat32 (grub2 config and iso images for loopback loading)
What I try is to get from the UEFI-Grub-Menu to start windows installation by pointing the chainloader to the other partition, my approach:
menuentry "Windows 10 Install" {
search --set=root --fs-uuid A1C7-8413 --hint hd0,gpt3
set prefix=($root)
chainloader +1
}
But the bootloader claims, that a wrong EFI path is set.
What am I doing wrong? Any hints welcome.
