Q: Cannot Boot from USB or DVD
Hello,
I cannot install or reinstall an OS because my Mac won't boot into anything apart from its hard drive. El Capitan boots up OK and I can use the Mac, but I want to reinstall the OS due to errors and I cannot put any OS from any boot device on the iMac.
So the problem I have is that I cannot reinstall the OS from USB or disc, nor can I put Linux on there.
Tails USB, Tails DVD, Mint DVD, Ubuntu USB - none work.
- All these .isos are tested and working flawlessly
- Have tried the disc & USB in 4 Macs - 1 MacBookPro and 3 iMacs. MBP works fine but none of the 3 iMacs can recognise it or boot from it.
- The disc was burned on one of the iMacs, also a USB came from a Win machine (so diff sources)
- If I insert the disc when I'm in any of the 3 iMac OS then I get a msg "cannot read this disc"
- On one of the iMacs I get a msg after boot saying "your computer was restarted bc of a problem" and I get the below err msg
