Windows is already installed on gpt, how can I install OpenSUSE without reinstalling Windows?

Question

Windows

With the purchase of a new PC, I decided to install windows 7 for games, I usually never installed it at times. First of all, I installed windows 7 so that there were no problems with restoring grub. Instead of mrb, gpt markup came out, which caused a problem - Grub2 requires a separate partition for efi, which must be created first, and there, in turn, there is already a Windows boot partition. How to keep windows 7 and install OpenSuse on the same drive? With mrb, by default, it was not required to mount a separate partition in /boot

Answer 1

If the markup is gpt, then Windows is loaded via EFI, and not legacy mode? Then Windows has already created a partition for efi and put its bootloader there. You just need to put efi for grub in there.

Answer 2

In general, I installed opensuse on ssd, mounted /boot/efi on another hard drive, everything was fine, but another problem arose - grub2 does not find Windows. Windows sections did not touch. I tried to enter roughly in the configs, something like this:

menuentry "Windows 7 (loader) (on /dev/sda2)" --class windows --class os {
insmod part_msdos
insmod ntfs
set root='(hd0,msdos1)' (This is sda2 - drive "C:" with Windows)
search --no-floppy --fs-uuid --set= root
98CCC050CCC029F8

but in the end I get

Invalid EFI file path
