I had a single boot installation of Redhat 9.0 and decided to convert to Fedora Core 4 as an upgrade. It has given me nothing but problems. If I do the upgrade from 9.0 it will not boot. So I did a new install with Fedore Core 4 and did an automatic partition, deleting all other partitions. When I do, the system boots to a grub> promt.

I'm a little new to Linux, but I don't understand why this would occur on a new installation. I've tried upgrading the grub boot with the old 9.0 disks, as well as changing the options with the new Fedora Core 4 disks. I have only this drive installed with this one distibution of Linux.

Any help would be greatly appreciate. Thanks.

use the fedora firs cd as rescue and reinstall the grub ot the mbr read this link

I tried step six of your guide, "How to reinstall the grub to mbr or root partition?"

I followed the directions, and even did it over again with other options drive numbers, to make sure that I did it correct.

With the root (hd0,x) command I got:
x=1 Filesystem type unknown, partition type 0X83.
x=2 Filesystem type unknown, partition type 0X83.

With the setup (hd0,0) command I got:
as 0 Error 17: Could not mount selected partition.
as 1 Checking if "/boot/grub/stage1" exists. . . no
Checking if "/grub/stage1" exists. . . no
Error 15: file not found

I'm not proficient with Linux, but when I installed Fedora my partitions did look a little weird. There was some LVM Volume Groups listed first, and that is where the grub was pointing to o the install. I tried doing an upgrade to Fedora and changing the grub bootloader there, but it says something about not being able to find a Kernel or something.

Thanks for your help so far.

I've installed again with the same problem. Does anyone have any thought as to what I should try next. I've been working on this for the last week now, and I'm about ready to call it quits for a while and come back to it.

try to boot from grub prompt read http://shamsweb.50webs.com/page3.html#grubp

Personally I'd try installing with manual partitioning, and avoid using LVM. It caused me problems on my last install too.
