Craig responded: boot the F10 DVD - choose 'Rescue mode' and do not install again <<<<<<<<<<< Accept the default options and it should locate the Fedora 10 installation automatically and leave you at a command prompt Type... chroot /mnt/sysimage grub-install /dev/sda exit exit remove the DVD and it should boot into F10 If not, please post the contents of /boot/grub/grub.conf Craig -------------- jbyers did above, it found the install, but the response was exactly or nearly so as my last attempt: --does not give the /dev/root error instead flashes a full screen of boot msgs which quickly disappear then the screen remains blank, have to hit power. --it is possible still finallly hittting that /dev/root error but screen goes blank so fast I cant tell. So, your procedure seems to do no more than my last one. here is the grub.con # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You do not have a /boot partition. This means that # all kernel and initrd paths are relative to /, eg. # root (hd0,0) # kernel /boot/vmlinuz-version ro root=/dev/sda1 # initrd /boot/initrd-version.img #boot=/dev/sda default=0 timeout=0 splashimage=(hd0,0)/boot/grub/splash.xpm.gz hiddenmenu title Fedora (2.6.27.5-117.fc10.i686) root (hd0,0) kernel /boot/vmlinuz-2.6.27.5-117.fc10.i686 ro root=UUID=449a78aa-d4d5-4 e91-bf9c-5833d7218c8f rhgb quiet scsi_mod.scan=sync initrd /boot/initrd-2.6.27.5-117.fc10.i686.img this is the grub.conf produced by my install, but previously modified by me to append scsi_mod.scan=sync the rescue chroot did show device.map (hd0) /dev/sda and said to repair it if necessary. I didnt do anything, I could add (hd1) /dev/sdb, but i thot it was not necessary for booting off of sda. One other thing i dont think i have mentioned before: the boot attempt first starts with something like acpi invalid[?] pblk.... doesnt stay on the screen long. I think i have seen this on every attempt. any other ideas? maybe retry taking out rhgb quiet? Jack
