I installed CentOS via unetbootin and USB stick. Unfortunately, I can not now start my system w/o my USB usb drive.

Can someone provide me with some information how to fix this?

Thanks.

This question came from our site for system and network administrators.

pull the usb stick out and run

# grub-install --recheck '(hd0)'
Probing devices to guess BIOS drives. This may take a long time.
Installation finished. No error reported.
This is the contents of the device map /boot/grub/device.map.
Check if this is correct or not. If any of the lines is incorrect,
fix it and re-run the script `grub-install'.

(fd0)   /dev/fd0
(hd0)   /dev/sda

pick your device and rerun (only if it wasn't recognized as hd0)

# grub-install '(hd0)'
Installation finished. No error reported.
