I have Windows 7 on /dev/sda and CentOS 6.4 on /dev/sdb. Here are the
layouts:
(parted) select /dev/sda
Using /dev/sda (parted) print
Model: ATA WDC WD10EZEX-00Z (scsi)
Disk /dev/sda: 1000GB
Sector size (logical/physical): 512B/4096B
Partition Table: msdos
Number Start End Size Type File system Flags
1 1049kB 374MB 373MB primary ntfs boot
2 374MB 1000GB 1000GB primary ntfs
(parted) select /dev/sdb
Using /dev/sdb
(parted) print
Model: ATA ST500DM002-1BD14 (scsi)
Disk /dev/sdb: 500GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt
Number Start End Size File system Name Flags

2 211MB 735MB 524MB ext4
3 735MB 500GB 499GB lvm
/boot/efi/EFI/redhat/grub.conf looks like this:
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this
file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.

# kernel /vmlinuz-version ro root=/dev/mapper/vg_amrl01-lv_root
# initrd /initrd-[generic-]version.img
#boot=/dev/sdb1

The system boots into CentOS just fine, but selecting the "Windows 7"
entry results in
invalid EFI file path
Error 1: Filename must be either an absolute pathname or blocklist
Press any key to continue...
By my understanding, since grub is installed on sdb, then sdb becomes hd0
and thus sda would become hd1, and so telling it to boot Windows from
hd1,0 makes sense. Also, since anaconda created the Windows entry during
the CentOS install, I would have expected this to work. However, as it
doesn't work, I'm clearly missing something. Can someome please point me
in the right direction as to why this isn't working?
Thanks!
