Centos 7.9 installation on DELL optiplex 7010 SSD installation-

[kumarmukesh]

Hi all
i need your help.
I tried to install Centos 7.9 on Dell optiplex 7010 using bootable USB but got following error.

-failed to set new efi boot target. This is most likely a kernel bug.

Configuration of DELL system
- Model - DELL Optiplex 7010, 1TB HDD, 512 GB SSD, 16 GB RAM
-installation was on done on SSD
- Installation Media - USB (centOS everything) creating using rufus (GPT partition)

During installation all major partitions like /boot, /boot/efi, /, /home were created. despite error, installation was completed. but now shutdown problems are coming as system get halted during shutdown and reboot.

Anybody pls help me in this regard.

Note- I am new in linux systems

Start by re-running this step NOT using Rufus. It is known to corrupt the CentOS isos as it copies them if the wrong options are selected. Use one of the tools listed on our USB Install wiki page (link in my sig below).

Thanks. I will try it

I'd also add that there isn't a huge amount of point in installing new CentOS 7 instances now. It has less than 6 months of life left until it goes EOL and is retired. You'd probably be better off installing something newer, probably best to use EL9 and one of the newer RHEL rebuilds listed in my SIG again.

Wikipedia claims that Dell Optiplex model was introduced "mid-2012" and had Intel "3rd gen Core".
If so, then the machine is older than EL7 but its CPU should already support even EL9.

The issue might be with UEFI (on the motherboard). Early UEFI implementations were less perfect.
Does the motherboard have the latest firmware version? Dell seems to have released something up to 2017:

The systems are latest one -(13th generation)
Mother board - Q670
512 GB M.2 NVMe SSD

Then it's probably too new for CentOS 7 which came out in 2014 and goes EOL in about 5 months time. You'll be reinstalling with something newer in 5 months so why not just use that now?
