CentOS keeps giving back installation after reboot

Post by ronel » 2021/10/19 17:05:53

I am installing CentOS 7 on HP Proliant ML110 Gen9 server. I completed the installation and after rebooting in the Boot Menu when I select CentOS it redirects me to System Utilities
And If I select exit and resume system boot it starts the installation process again.

If I go ahead with the installation again the disk has partitions from the previous install

(I am unable to attach the image, file too large)

Any help is appreciated.

Eject the DVD from the drive. Or go into the BIOS settings and change them so it doesn't attempt to boot from the optical drive first.
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.

OK, so it's a USB stick you are using. How did you copy the iso image to that stick? Look at my sig for a link to our wiki USB install page which details several utilities that do not work. They corrupt the UEFI/Legacy BIOS dual boot that is built into the iso image and that forces it to boot in Legacy BIOS mode even on hardware that is in UEFI mode. The install then proceeds as though it's on a Legacy BIOS machine and the machine will try to boot it in UEFI mode and weird stuff happens.

However, if it's repeating the install every time then your USB stick must still be in the machine. There is no software eject for a USB stick so unless you physically remove it then it's going to boot from it.
