I own a really old iMac Desktop from 2011, and I’ve been having a problem booting it up. I get stuck in a boot loop, and I don’t know what to do. Sometimes I get out of the boot loop, and the bar loads up to 95% at a slow rate and it doesnt move after. Please help.

Might search your Area for an AASP.
Sounds like the drive it dead.
Can you put the working on in Target Fisk Mode
holding t key at startup, then on the non-working one hold alt key at startup to see id the bad one can starup ising the good one's drive?
Is this it?
Do you have a Time Machine backup to Restore to/from?

All those 600xF errors are some Network/Internet problem, some have had success using Ethernet instead, some by setting theDate/Time, some end up taking it to Apple. :(
Try these strartup keys...
Safe Boot from the HD, (holding Shift key down at startup), does the problem occur in Safe Mode?
Recovery mode... CMD+r keys
Verbose mode... CMD+v keys * see if you can tell the last lines on screen.
2018 imac is in a reboot Cycling. I cannot get into recovery or safe mode. Have connected 2 macs with thunder bolt and cannot get the target disk to show up on second mac. Cannot take imac to store during quarantine either.
any suggestions?????
Any luck yet?
i used recovery mode, and im trying to reinstall a newer version of mac. but i cant seem to install it because my disk is locked. is there any way to unlock my disk so i can re install a newer version.
I am experiencing the same problem on my 2012 Pro. After keying in CMD + V, the first screen reads "The system was automatically rebooted after a panic" then another screen of lots of text loads, then it reboots automatically and continues its loop. I tried CMD+R but it comes up with a 6002F error after the apple symbol loads and loops again.
