OK, I now have the new disk. Unfortunately, it turns out that GPT is

You need to boot Windows directly via EFI, and linux via an EFI
elilo or grub-efi or grub2 loader (elilo.efi/grub.efi/grubx64.efi in
the EFI-boot-partition).
See: http://www.rodsbooks.com/efi-bootloaders/index.html
And if Grub can do it, then it's much more difficult to set up
compared to a BIOS boot. I surely don't have a clue as to how to do
that.

I settled with an MBR-based boot solution and MSDOS partitioning, like
before. It's easy to setup. The whole EFI multiboot setup does not
seem worth the effort to me. If it was easier to setup, I'd go for it,
but as it stands, it's a nightmare to work with.
