Thread: Help oldfred! Dual Boot issue here

i have uefi/gpt computer 3 drives, sda linux xubuntu 12.04 (efi partition on sda1), sdb formatted ext4 data, , sdc formatted ntfs data. added 4th drive, sdd , installed win 8 (sda unplugged during install). win 8 install created efi partition on sdd1. plug sda , set boot drive, boot linux , run boot-repair. when reboot grub, won't boot windows. grub entry looks wrong untrained eye:

menuentry "windows 8 (loader) (on /dev/sdd1)" --class windows --class os {
insmod part_msdos
insmod ntfs
set root='(hd3,msdos1)'
search --no-floppy --fs-uuid --set=root d8c2389fc2388432
drivemap -s (hd0) ${root}
chainloader +1

, here full report boot-repair:

edit: 2012-11-2 followed suggestions in thread, used gparted delete efi partition sda1 , make bios-grub boot partition. ran boot-repair , xubuntu 64 bit , win 8 pro 32 bit both boot grub menu expected.

it not put me in title.

better boot-repair.

grub2 os-prober makes bios type chain loader entry. yann has updated boot-repair add correct chain entries windows file in efi folder. adding 3 entries windows files & 2 worked posted several users.
