Hi there,
I’ve got this problem with my Windows partition not appearing in the Grub2 boot menu for quite some time now, but now as I’ve started booting into Windows more often (using it mainly for music production), hitting ESC like crazy when booting to switch the boot drive has really become pretty enerving. So I hope you can help me figuring out how I can make Grub2 boot my Windows without abusing the poor ESC key anymore.
I’m running OpenSuse 13.2, installed on /dev/sda and Windows 8.1, installed on /dev/sdb.
My Windows drive has partitions sdb1 with 350MB (with the boot manager) and sdb2 with the actual Win8 installation, both NTFS drives. The content of the bootmanager partition sdb1 does not look like a EFI partition as I would expect:
drwx------ 1 frank users 8192 Sep 12 15:48 Boot
-rw------- 1 frank users 404250 Jun 14 2014 bootmgr
-rw------- 1 frank users 1 Jun 18 2013 BOOTNXT
-rw------- 1 frank users 8192 Aug 26 22:40 BOOTSECT.BAK
drwx------ 1 frank users 0 Aug 26 21:42 Recovery
drwx------ 1 frank users 0 Aug 26 21:41 System Volume Information
The yast partitioner tells me that sdb is not a GPT drive but MSDOS, hence my additions to the menu file (see below) are probably failing.
What I’ve tried this far:
-
I’ve tried os-prober as suggested on some websites (with and without mounting the windows drives before) without any luck.
-
I’ve also added menu entries in /etc/grub.d/40_custom:
menuentry "Windows" {
insmod part_gpt
insmod chain
set root='(hd0,gpt1)'
chainloader bootmgr
}
menuentry "Windows 2" {
set root='(hd0,gpt1)'
chainloader +1
}
Neither entry works.
Any kind of idea how to go about this??
Thanks a ton in advance!
