[SOLVED] GRUB problems after fresh install

mibadt · 2013-12-18 11:19:58

Hi,
Due to a HD failure I had to re-install Arch (64b) (using the latest Dec 13 version).
It's a dual boot, dual HDs where sdb was MBR partioned and contaings among others, Win7-64 on sdb1 and /boot on sdb2. (details below)
Due to it's size (3TB) the second (sda) drive was GPT partitioned and includes, among others, the (Arch) root on sda2. (ditto).
I've installed grub (2) to sdb.
After finishing the first installation phase and trying to reboot from the fresh installed Linux (First boot from HD, not the install media), I get only two grub entries (linux and fallback), yet both seem wronly confiured and can't find the linux image.
Besides, although I've installed os-prober prior to the GRUB phase, it failed to add a respective Win to GRUB's menu.
Please advise!

Thanks !
Note: The Windows has originally been installed on an MBR-disk and, in order to avoid the need to reinstall Win, I've kept sda-MBR.

Relevant terminal output:

Solved!

I've noticed that grub.cfg was dated several months ago, while grub.cfg.new was dated today (install date).
I've swapped these two files, chrooted, and reinstalled GRUB.
Now GRUB's menu works fine, although still no Win menu entry.

Regards..

Arch Linux
