I have a new desktop and it runs Win7. On my old pc ran Vista and Ubuntu 10.04 no problem in dual boot config. Looks like Win 7 does a registry check because after a good boot up in Ubuntu and Win 7 does a check then boots ok but when I try to boot back into Ubuntu it say something about a target not found. Any Ideas? Also may haveto repost later as old printer not compatable with Win 7.
