Boot Win10 from an ISO-Image on a certain partition using GRUB2
I have bought a laptop (Lenovo ThinkPad T520) with a locked BIOS. So I can't change the boot order of the laptop. The upmost device in the boot order is the internal HDD. Fortunately there is a working Linux with Grub2 installed, which I have access to.
I also want to install Windows 10 now. How do I have to change the Grub2-configuration in order to be able to boot the Windows-installation from a Win10-Boot-Medium (ISO)?

To boot the Win10-Image from your HDD:
- Add the below code to
/etc/grub.d/40_custom
- Back up
/boot/grub/grub.cfgwithsudo cp /boot/grub/grub.cfg.bak. (Or add a number, if there already is agrub.cfg.bak.) - Then run
sudo grub-mkconfig -o /boot/grub/grub.cfg.
Grub2-configuration:
menuentry "Windows 10" --class windows --class os {
# Insert modules needed in order to access the iso-file
insmod part_gpt
#insmod part_msdos
insmod ntfs
#insmod ext2
# Insert module needed in order to find partition
insmod search_fs_uuid
# Set UUID of partition with the iso-image
# and let grub2 find the partition
# (save it's identifier to the variable $root)
set uuid="XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"
search --no-floppy --set=root --fs-uuid $uuid
# Mount the iso image by addressing it with (partition)/path
set iso=/images/Win10_English_x64.iso
loopback loop ($root)$iso
# boot (chain-load) the image using the cdboot.efi file located
# on the win10-image
chainloader (loop)/efi/microsoft/boot/cdboot.efi
}
Instructions:
Replace XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX with the UUID of the partition, that holds the Windows 10 image.
insmod part_gpt: This module is needed, if the Win10-ISO-Image lies on a drive with a GPT-partitiontable.
insmod part_msdos: Choose this one over insmod part_gpt, if the image lies on a drive with DOS-partitiontable.
insmod ntfs: This module is needed, if the Win10-ISO-Image lies a NTFS-partition.
insmod ext2: Replace insmod ntfs with insmod ext2, when the image lies on a ext2/ext3 or ext4 partition.

I have a system that boots in Legacy BIOS mode. I have an iso on an ntfs partition so I choseinsmod ntfsand choseinsmod part_msdos(and in a separate attemptinsmod part_gpt1) but I geterror: invalid signature` which my research shows has something to do with UEFI. WHich seems to relate to cdboot.efi. What should I use for legacy bios mode?
