Just take a CentOS DVD , select troubleshooting and then once you drop to a shell -> you can mount /proc/ , /sys , /dev & /run with the bind option and chroot.
Then just follow the procedure for your boot type EFI vs Legacy and recover the files missing. Best Regards, Strahil Nikolov В събота, 25 септември 2021 г., 12:41:27 ч. Гринуич+3, <[email protected]> написа: Hi all, I am new here, been searching the mailing list on a regular base when I encountered problems and till now I always was able to keep the system up & running. As said... till now... I have oVirt at home, and I have about 7 vm's running on it. Lately I have had some troubles with my electricity, which results in a complete power outage on a irregular base. Yesterday I had a power outage which left the system unbootable with the following errors: error: ../../grub-core/loader/i386/pc/linux.c:170:invalid magic number. error: ../../grub-core/loader/i386/pc/linux.c:1418:you need to load the kernel first. Press any key to continue Normally this can be solved following https://access.redhat.com/solutions/5829141, but his time also the files in /boot had a size of 0 bytes. So basically i did not have a working kernel on the system anymore. https://www.thegeekdiary.com/centos-rhel-7-how-to-install-kernel-from-rescue-mode/ does work for CentOS 8 also, but the ovirt 4.8 iso does not have the same directory structure. Using CentOS 8 installs a kernel, but not a bootable system. Is there a way i can start the installer in troubleshooting mode so I can reinstall just the kernel on the system? _______________________________________________ Users mailing list -- [email protected] To unsubscribe send an email to [email protected] Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/[email protected]/message/UUPMHNC7BQ62RK4BI5MFMZIPF6DDJLXJ/ _______________________________________________ Users mailing list -- [email protected] To unsubscribe send an email to [email protected] Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/[email protected]/message/Z54T56SE67DIBT46TCC63626NLQEJKAH/
