 Posted: Tue Mar 23, 2010 1:10 am Post subject: Blank Grub screen |
 |
|
Hi. I've got a very new HP Pavilon Elite (i7) at work. The other day I installed Gentoo amd64, and I had some issues with LVM but was able to work those out, and boot just fine into a new system. After that, however, we realized that the Elite has a hardware RAID controller, so we put in another drive, set up RAID 1 through the built-in configuration utility, and then re-installed Gentoo. Did everything the same as before, but this time after booting up, I just get the word GRUB on the screen, followed by a blinking underscore:
No grub menu, or anything.
Anyway, I googled into it a bit, and it seems like there may be some problem with the way that GRUB interacts with the systems RAID drive selection system (and no, I really don't understand it). I can boot into the LiveCD just fine, and mount all my partitions no problem. I tried running grub-install again, just for kicks, but that didn't change anything.
Next shift, I'm going to try installing perhaps grub2 or maybe lilo (never tried either before) because that is the only thing I can think of to do. But I thought I would check here first and see if anyone had run into anything similar before.

| So you are going to need an initrd/initramfs. A reference is here. |

| Could you post the output of "lspci -k", so we can see exactly which RAID controller you are dealing with ? |

Ok, your controller is of the BIOS-RAID variety.
If you are sharing the array between Windows and Linux, then you should look into dmraid and the related HOWTOs.
If you don't care about Windows, then you should disable RAID in the BIOS, and use native Linux RAID instead. |
