I have an Intel i7 based desktop (HP Compaq 8200 Elite) which I used to run on Ubuntu 14.04 for the past 4 years. Last week the Grub menu appeared but Ubuntu didn't boot. After couple of restarts the Grub menu also stopped appearing. Just a blank screen with a blinking cursor. I connected a graphics card to eliminate the possibility of on-board graphics failure; but no good.
I tried the following:
- Tried to boot the HP from an Ubuntu 18.04 pendrive - Didn't boot.
- Tried to boot the HP from another HDD with CentOS - Didn't boot.
- Connected an HDD with Win7 - System booted without any issue.
- Connected the Ubuntu HDD on my laptop - Ubuntu booted without any issue.
Assuming the issue is with by HP i7 desktop, I connected the Ubuntu hard disk drive on two other HP Compaq 8200 Elites, both running Windows. Both didn’t boot; similar behaviour; blank screen with blinking cursor.
Then I connected Ubuntu hard disk drive to another Intel i7 based machine (not HP); which booted without any issue.
I am completely puzzled by this behavior. What could be wrong with the HP i7s desktops, which is stopping Linux from booting ?

I have just done an install of Xubuntu 18.04.2 onto a HP Elite 8300 and to get to the login screen I have to press Ctrl Alt Delete *two* times to get it to progress on from seeing a black screen with a flashing cursor on the top left. Once I do this it works perfectly. This is with the EFI options enabled and legacy disabled.
I installed from a dvd using the desktop's internal dvd drive.
This issue is not present when using Windows 10 1803.
So hope this helps someone. I spent a lot of time trying different things in the BIOS to do with legacy and EFI boot options & then found all I had to do was Ctrl Alt Delete & repeat that once it had gone back to the flashing cursor.
