 |
|
Ok, well you might remember how I forgot to install Portage. So, I went back and redid that installation. Now, I have another problem. This is something really weird that I have never seen in my two years using Linux. This problem involves GRUB.
GRUB is configured to dual-boot Gentoo 64 and Windows XP Home. The problem is I can't get into Linux. I get an "Error 15: File Not Found". Secondly, my display is also screwed up with GRUB. At the start, when there is supposed to be a nice graphic, I get these different color rectangles and while selecting Linux or Windows, I get a display but it has all these lines.
I'm pretty sure this has something to do with my grub.conf as any newbie could figure out.
| Code: | default 0

splashimage=(hd1,1)/grub/splash.xpm.gz

I used genkernel. I have a SATA drive detected as /dev/sda which is divided into two partitions. This doesn't concern Linux. However, I have a SCSI/U160 drive detected as /dev/sdb. This is broken down into two partitions: /dev/sdb1 for swap and /dev/sdb2 for root partition.
Please check my grub.conf for anything that would cause the bad video I described and the file not found error. Any help is appreciated. [I have reiserfs driver installed in Windows so I can change anything from there.] |

Your root=/dev/sdb2 needs to be root=/dev/ram0.
As for you video problem, I guess your video card doesn't like whatever video mode Grub is trying to use. You have probably already done this, but as a workaround, you can comment out or remove the splashimage line. That should at least allow you to see the options. |

| If your BIOS is configured to boot from /dev/sdb rather than /dev/sda , then you need to reverse all your drive numbers in grub.conf too (i.e. make all occurrences of (hd1) into (hd0) and all (hd0) into (hd1)) |

| My BIOS doesn't boot from /dev/sdb as it is a SCSI drive and I haven't figured out how to get it to boot yet from the SCSI. Thanks, guys. See if this works. |
