I installed CentOS on my machine from my USB. I did a minimal CentOS USB drive with UNetbootin. After I install the CentOS, when i try to reboot, it does not starts. I have only the cursor blinking on a black screen.
Note: If I install the boot loader on flash drive, the system starts correctly when the USB drive is plugged in. But if I install the boot loader on HDD, I can't boot.
Can anybody help me on solving this issue?
EDIT 1 After I installed the boot loader on USB drive, I can log in (even if I unplug the flash drive after grub menu, I can load in). Here is explained what I did after I did this:
outputs (show only last lines):
(hd1) /dev/sda (hd0) /dev/sdb
this is the content of /boot/grub/device.map file.
Now if I run
reboot without the flash drive plugged in, I get this message:
failed to read image
