And w h y did you decide that was a good idea?! Please install grub from a live dvd or form command line. –Rinzwind May 17 '15 at 8:18 Now I am on grub menu, can i install grub from here. And right now I have no live boot mediums –TechJhola May 17 '15 at 8:21 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote So you've messed with GRUB. One easy, fool-proof solution (if not the fastest) is to install Boot Repair. Follow their instructions. If you've managed to get a shell prompt, you might be able to run apt-get commands. Or grab an Ubuntu live CD (tricky if this is your only computer), boot from it then live install Boot Repair (see 2nd option paragraph). It works miracles. If you're feeling lucky, have a look at the GRUB troubleshooting page, but this assumes you already know your way around your partitions. This page contains interesting commands. The trick is to find out what X and Y values to use. Don't ever mess with GRUB unless you know what you're doing. And of course, backup your disk before experimenting. Should anything go wrong, you can still restore it. Less pain at the end of the day. share|improve this answer answered May 17 '15 at 8:34 youri 49559 add a comment| Your Ans

I decided to install Ubuntu 11.10 mini instead of Lubuntu 11.10. After the installation the operating system didn't boot. I only saw the black screen. I used sysresccd and tried to repair grub according to this guide and I tried solution 2. It didn't help. I tried to repair it with lilo. I remembered that at some time in the past I repaired mbr with lilo and everything was OK. After using the command: lilo -M /dev/sda mbr http://unix.stackexchange.com/questions/31032/unable-to-boot-the-operating-system I restarted the laptop and a message appeared (I don't remember what it said). I understood that I had to install grub again and repeated the procedure with sysresccd, which didn't help. EDIT: fdisk -l /dev/sda EDIT: content of /boot directory of sda1 partition EDIT: I used google and found this link. It seems that this is my problem. It was only sufficient to press ctrl+alt+F1 and Ubuntu started booting. After commenting the line containing vt.handoff in /etc/grub.d/10_linux everything was OK. How to close this question? boot grub2 mbr rescue lilo share|improve this question edited Dec 27 '13 at 1:07 hildred 3,68811233 asked Feb 6 '12 at 16:14 xralf 1,483134896 It will be much easier for someone to help you if you reboot the machine again and take note of the error message. –Teresa e Junior Feb 6 '12 at 17:18 the error message was something like "no operating system found". You won't get more information from it. I understood it that lilo cleared mbr, so I reinstalled grub. –xralf Feb 6 '12 at 17:35 Please boot from rescue-cd and post the output of fdisk -l /dev/sda. –Nils Feb 9 '12 at 21:18 @Nils See question edit –xralf Feb 10 '12 at 9:26 Can you post your /etc/fstab ? –Neel Basu Feb 10 '12 at 11:01 | show 7 more comments 4 Answers 4 active oldest votes up vote 1 down vote Boot from a Live CD.
