I have three different distros on here1 Windows10 Linux Mint on one SSD. Garuda Linux on another one, I also tried an external T5 with Windows 10 on it. But now I can,t get any of them to load up. I have tried ESC and F9 but nothing shows on there, also I get beeping when pressing ESC. and F9 I was surprised that the T5 loaded. I also have a 2TB hard drive in the PC. Why is nothing showing when I press ESC and F9? I took the original hard drive with Windows on it out. I was intending to clone it to the Windows10 Linux Mint and just make that Windows. But I took out the hard drive with Windows on it out. It did load the Windows and also loaded Mint. Then I tried the T5 external drive then I got the problems with not getting any of the boot options pressing the ESC and F9 i forgot also the F2 key. Can,t the PC handle three drives in it? When it first happened I thought there was a bad connection somewhere I checked. I am not getting the bleeping now, but the yellow light on the PC has gone off?
