I'm new to the Linux world so please bear with me! :-)
I installed Ubuntu via USB drive onto my hard drive. If I boot the PC without the usb drive I used, Ubuntu will not load. After booting I can unplug without any consequences.
I looked on the hard drive and there is a boot folder. On the USB drive, this is the tree contents:
/media/disk$ tree . |-- adtext.cfg |-- boot.cat |-- f10.txt |-- f1.txt |-- f2.txt |-- f3.txt |-- f4.txt |-- f5.txt |-- f6.txt |-- f7.txt |-- f8.txt |-- f9.txt |-- initrd.gz |-- isolinux.bin |-- isolinux.cfg |-- ldlinux.sys |-- linux |-- menu.c32 |-- menu.cfg |-- po4a.cfg |-- prompt.cfg |-- splash.png |-- stdmenu.cfg |-- syslinux.cfg |-- text.cfg |-- ubnfilel.txt |-- ubnpathl.txt `-- vesamenu.c32
Am I correct in my assumption that the boot aspect is associated to the USB drive? If so, how do I get it to boot without the USB? I'm guessing copying into some location and modifying grub?
