My progress after installing linux knoppix on my hd(need hlp

well, first i installed linux on my hdd, iv got some troubles first but i could solve them
now i have another problem...
the hd i used was a laptop hd, so i pluged it as usb on a desktop computer, and installed it through that, after i connected it into my laptop, i got some issues...
first, the root was sda, - i solved that ->hda1
it was read only (and i still dont know why), i solved it # mount remount,rw /
..now here i cant solve anything
the line begins with (none) root@none
i cant access anything, i need help for that
anything?

dunno, all i need is to boot knoppix all from the hd.... troubles r coming from nowhere, i lv learning that, better than the boring windows/dos
