U330 System Image = System recovery disk?

Question

hi all
i have created a system image into a portable external harddisk for my U330 laptop.
once that is done, i was prompted if i want to create a system recovery disk.
just wondering, do i still need to create a system recovery disk if i have already created an image?
if i want to recover my system, just plug in the hard disk containing the system image during boot-up, and follow the onwards instructions?
also, in what ways is this way of recovering different from the one-key recovery by Lenovo?
pls advise.

Answer 1

if windows vista installed, run one-key recover 6.0.
already got backups, skip "back up" otherwise click that.
select full backup, quick compression and next >
choose the path or leave it default and next >
and start.
after back up ends, restart the application one-key recover 6.0
click "create recovery disc" and next >
select the backup you have and next>
this screen will tell you how much cd or dvd you need, min 2 dvd or 8cd, max 7 dvd or 28 cd. and next>
insert the blank cds or dvds into driver and wait until done.
you may need the system image, you can lose your back-up cd, or  cds may not working after a while, so , i still recommend that you keep the original copy or more than one backup.
size of recovery  cd depens on how much size of disk space you use. its up 2-7 dvd or 4-28 cd.
after upgrading to win7, have you seen new part of hard disk such as lenovo system and backup files included?

one-key recover 6.0 doesn't work on win7, at least for me, but you can try.
i got error when i want to ""an internal program error has occured error code : 0xe0dd001f."
and for that, i'm still working on and waiting for the solution.
