Thanks for ur reply, Let me be little clear in explaining the problem to u. I have redhat 9 installed on machine A for ex which was workin fine and sudenly when i reboot the other day it refused to boot giving me segmentation fault. the things i have done are I moved the HDD to another identical machine (same model say machine B ) and it gave me the same problem. so obviously the problem was either linux OS being curropted or HDD problem i can use linux in rescue mode and all partitions are mounted and all the data is fine now i tried to upgrade redhat 9 when everything goes fine until the screen where it shows me the packeges being copied . its starts with lernel packafe the first one and after completing it .. it jus stops . does not go forward. i even tried deleting all files in the /boot partition but same problem. now i was think of formating the boot filesystem only and resinstall linux again.. will it affect the data on my other partitions.. or apprecite if u cd sugest me some other step thnks and appreciate regards simon David Tonhofer <d.tonhofer@xxxxxxxxxxx> wrote: sylvan dacounha wrote: > Hi All, > > in my earlier mail i had mentioned that i am not able to boot redhat > linux 9 cause it gives segmentation error > > [...] > i have data which i dont wanna loose . > Hi, I suggest running memtest86 (from a bootable CD) on your machine and/or installing Fedora Core on a new machine, then move your existing harddisk to the newly installed machine and read your data off the disk on there.
