Now I am in a situation as follows. I have got a PC and 10 GB HDD which will be totally dedicated to Ubuntu so no option of Wubi and dual boot. I was trying to install from DVD, but it is getting stuck at "Out of frequency" error. So I had

to adapt for USB boot option. But my PC is USB non bootable, so workaround is "Plop Boot Manager". So I am doing the installation procedure as follows: starting from a CD drive which is having plop installed. opting for for USB boot in plop options. booting begins from USB. monitor eventually gives "out of frequency" error press Shift+Alt+F1 to get the terminal. open the grub with sudo nano /etc/default/grub. do necessary changes. sudo update-grub. Now here I am getting error as follows: /usr/sbin/grub-probe:error:failed to get canonical path of /cow. My system is P4 3.06 GHz, 1 GB ram , 10 GB HDD without an OS, monitor CRT lg StudioWorks (7 years old). Mobo Mercury P4 266a NDMx (865 equivalent). The whole system is perfectly in working condition under XP, but it is USB non bootable, and all other devices working perfectly.

So, GRUB detected that /zroot is a ZFS (otherwise, how did it know about ata-QEMU stuff?), but if fails to resolve correct path to device. OK, let's try to fix it in a dirty way: # ln -s /dev/sda /dev/ata-QEMU_HARDDISK_QM00001 # grub-probe /zroot grub-probe: error: unknown filesystem. # grub-probe -vv /zroot grub-core/kern/fs.c:56: Detecting zfs... grub-core/osdep/hostdisk.c:319: opening the device `/dev/sda' in open_device() grub-core/fs/zfs/zfs.c:1183: label ok 0 grub-core/fs/zfs/zfs.c:1183: label ok 1 ... grub-core/kern/fs.c:78: zfs detection failed.

Posts: 31 Reinstalling Grub This MIGHT be a simple fix, but I'm hoping to get someone else's opinion before I unleash any more demons on my computer. I'm trying to fix GRUB. I'll post some background info to explain exactly what has gone wrong:I decided to do https://bbs.archlinux.org/viewtopic.php?id=201380 the "update" to Windows 10 on my laptop. After it downloaded about 2%, I got https://bugs.launchpad.net/bugs/1527727 the blue screen of death. It rebooted and thankfully Windows still booted up perfectly fine. Still, I decided that I'd had enough of Windows for the time being, so I chose to forget about the Windows 10 update and to go back to trusty Arch instead. But after I tried booting up Arch, I got some nasty error messages. I didn't failed to write them down (and kicking myself for that), but it was something terrible like "/dev/sda does not exist." And then I got the infamous:Bailing out, you are on your own. Good luck.followed by the BusyBox shell prompt."/dev/sda" is an ssd with Arch on "/dev/sda1" (ext4) and Windows 7 on "/dev/sda2" (ntfs). I haven't done any major updates on Arch in the past couple of days, no kernel updates or anything. Before trying to run the Windows failed to get 10 update, I double checked that everything on my Arch partition was working and I backed up my most important files to another drive (thankfully).I had a flash drive of Fedora 22, so I booted that up and ran "fdisk -l" to make sure that my ssd hadn't quit working. The output looked exactly as it should, so I'm guessing that the drive itself still works fine. I thought maybe there was a problem with GRUB, so I tried reinstalling it through the flash drive:sudo mount /dev/sda1 /mnt sudo grub2-install --root-directory=/mnt /dev/sda^ This command reported Installation finished. No errors detected.This method has worked for me before (on Ubuntu, at least), but after booting up, I just get a GRUB prompt. I had the idea that maybe the "grub2-install" command in Fedora is different than the "grub-install" command that Arch uses. Is that possible? If so, I have an Xubuntu iso on another computer and can make a bootable flash drive from it right now. Would it be worth a try to run the above commands through an Xubuntu flash drive (replacing "grub2-install" with "grub-install")? Would it be better to download an iso of Arch and run some chroot commands to reinstall GRUB? Or is there a better option I'm not thinking of?I haven't booted up Windows in months and have had 0 problems with my co
