Hello
Please check out how my SSD is structured, note "DEV" is Windows 10, and "DAW" is also another Windows 10. Yes I have two Windows 10 installs on one EEFI hard drive.
nvme0n1
├─nvme0n1p1 vfat UEFI D4F4-1F7A 871.3M 8% /boot/efi
├─nvme0n1p2 swap b18a8de1-5fe2-413b-8605-813c5baa77c0 [SWAP]
├─nvme0n1p3 ext4 UBUNTU 77018d89-077f-4076-9f2f-ba385addce9b 124.5G 8% /
├─nvme0n1p4 apfs 775b62e8-2e49-45d4-8460-46c7c8a79859
├─nvme0n1p5 ntfs DEV EA3414BA34148C27
├─nvme0n1p6 ntfs DAW 7C8473EE8473A8F2
└─nvme0n1p7
This boots one Windows partition:
# This entry works fine but only boots Windows on one partition.
# I need to boot the second Windows partition as well. Hence new boot entries below.
# Note this is the only thing detected with sudo os-prober:
menuentry "DAW - Windows 10" --class windows --class os {
insmod part_gpt
insmod fat
search --no-floppy --fs-uuid --set=root D4F4-1F7A
chainloader /EFI/Microsoft/Boot/bootmgfw.efi
}
How can I direct boot the other Windows partition from Grub? I don't think I can unless I boot Windows and use the Windows bootloader.
Please note I am NOT using MBR!! I had this working fine under MBR but I've since moved to GPT.
Thanks!
