Hi Unman, Yes, I overwrote all entries while installing Ubuntu. Thanks a lot for your hints, problem is finally resolved after hours of reading :) What I done chroot /mnt/sysimage cd boot grub2-mkconfig grub2-install /dev/sda reboot Old grub file was fine so I booted in now successfully.

At a pinch you could do this by using the rescue disk - the data in your qubes is stored in /var/lib/qubes - each qube has a separate directory and the data is stored in the private.img files. (I think you said you can access /mnt/sysimage using the rescue disk.) You can either copy the private.img files off the system, or mount them individually and copy off the data. When you installed Qubes you had a separate /boot partition - probably at /dev/sda1 - you can check this (if you are not sure) from rescue mode. I assume that you overwrote the entries there when you installed Ubuntu? What you need to do now is to generate a new grub configuration, make sure it is installed to /dev/sda1 (or wherever) and then update grub. What is the error message you are getting? I know this seems daunting, but if you take it step by step you should be fine, professional or not. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

Re: [qubes-users] Re: Fixing BOOT of Qubes OS
Guys, Thank you for your replies. Unman, Ubuntu is not important to me. Most important thing is to load Qubes again. I have tried grub2-install /dev/sda3 - but I am getting an error saying that it's unreliable and system will not go further. I also done grub2-install /dev/sda successfully, but when I am starting laptop - it gives me grub rescue message that cannot load system. I don't have so much knowledge to resolve further. Please advise how I can restore qubes loader on my laptop? Thanks a lot! TO the user: damm swing. Thanks for your suggestion, I will try that as the last option as I don't have a spare system to install qubes to. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

You can load rescue mode and reinstall grub2 from there: the fact this is legacy boot doesn't matter. Before you reinstall grub, take a copy of the existing file for the Ubuntu install - you'll find that in /boot/grub2/grub.cfg. When you reinstall it *should* find the Ubuntu partition but just in case you will have the information there and can manually add it later. Have you looked at www.qubes-os.org/doc/multiboot ? Oh, and do make sure you have a backup, as damn swing says. unman -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
