I am out of ideas, using a purchased osdisc fedora 10 dvd reinstalled f10dvd media ck said ok this time using minimum options and this time accepting default of mbr sda install said successful but on reboot get exactly same errors as seen previously when f10 grub into sda1 notmbr , (then was using fc5 grub in mbr sda) this time there should have been no connection at all to my fc5 on sdb6 but get same boot error: cant access resume device (/dev/sdb2) mount: error mounting /dev/root on /sysroot no such file or directory so my hopes that my troubles were my old fc5 grub version .97-5 was confusing f10 hence preventing f10 booting, seem not to be the issue. I did find one suggestion on fedora common problems or? "to edit the kernel argument and append "scsi_mod.scan=sync" so i use knoppixcd to get my fc5 back: in grub root(hd1,5) setup(hd0) which is where i am now for this email, and mount the new installed f10 and edit its grub.conf as above then went back to knoppixcd root(0,1) setup(0) to get back to f10 knoppixcd out then rebooted again this time the f10dvdinst boot attempt does _not_ give me that dev/root one line error but instead a whole screen of boot msgs but then screen quickly goes completely blank, no response have to hit power button this last response says appending "scsi_mod.scan=sync" had some effect but I have no idea what else to try. Are there other scsi issues I should be aware of re f10? My sda, sdb are both scsi disks help, please I really would like to dump fc5, but i need a booting f10 Jack
