I am going to be as specific as possible. I recently purchased a dell precision m90 with vista business sp2 32 bit preinstalled. I cloned my internal hard drive (100 gb) using drivexml to a larger one (320 gb) so I could use the larger hdd as my new internal because I am running out of space. I created 2 partitions, both ntfs format on the 320 gb hdd. One for recovery and one for windows. I cloned the recovery partition on the 100 gb hdd to a 5.86 gb partition on the 320 gb hdd, and then cloned the windows partiton(C to a 280 gb partition labled windows on the new 320 gb hdd. The clone took about 3 hours and there were no errors. I did this using a sata/ide to usb hdd enclosure. I then safely removed the 320 gb hdd, powered of the dell, and swapped the internal hdd(100 gb) with the newly cloned 320 gb hdd. When I powered the dell on I went into bios with f2 and ensured that the internal hdd was set to boot first. After saving and exiting, the newly cloned hard drive would not boot. All I would get is a black screen with a small blinking dash in the left top corner of the screen. After powering off again and switching back the hard drives, I turned the dell on again and booted to windows. I then went into computer,manage,disk management, storage after hooking the 320 gb back up to my enclosure. What I noticed was that the recovery partition on my initial 100gb was active, and windows(C was not. Also on the active recovery partition it said EISA configuration. My question is do I have to set the recovery partition on my new cloned 320 gb hd as active in order to boot into windows when I use it as my internal hdd? I was told on other forums that by using the method of cloning I do not have to reinstall windows. I also have another 160 gb hard drive with a complete pc backup on it. How do I get my new 320 gb hard drove to work?I never knew upgrading a laptop hdd could be so difficult but I do not have a windows vista install disk nor the means to aquire one. Thank you to anyone who takes the time to read this lengthy post, and who can offer help.
