My laptop came presupplied with a Vista Professional installation and no Vista installation DVD. It has now stopped booting, stuck in a cycle of failing startup repairs.

I have a Windows 7 Ultimate DVD, but when I boot from it and select the option to upgrade an existing Windows installation, it states that the upgrade should be performed from within the existing Windows installation as a live upgrade.

Without being able to load the original Vista installation, how can I perform an upgrade to Windows 7 without losing my user accounts and installed programs?

Although I back up most of my data I really need to get the upgrade working in order to sanity check that I'm not losing anything important.

Thanks in advance.

Have you tried recovering your Vista installation using the Vista recovery disk? Download it here, burn it and boot from it.

@BloodPhilia: thanks for the link. I'm currently writing from my iPhone as I don't have another machine with a DVD writer until work tomorrow. Anymore suggestions until I can try this? – Brian Scott Jun 28 '10 at 20:55
    
@user17873 - No, if you want to perform an upgrade, getting Vista to work again will be your top-priority. – BloodPhilia Jun 28 '10 at 20:57

I've been reading that a clean installation actually copies the previous installation to a windows.old folder. Can aynone confirm 100% that I will have access to all previous user / desktop files after a clean installation? – Brian Scott Jun 28 '10 at 21:04

@user17873 - Yes all such information will be copied to your new installation. – BloodPhilia Jun 28 '10 at 21:06

@user17873 - The entire user profile of every used should be retained, this includes documents, desktop, etc. everything in C:\Users probably. I would recommend on backup up before though... there's always a chance something goes wrong. – BloodPhilia Jun 28 '10 at 21:24

You will have to repair the Vista installation to do an Upgrade to preserve your accounts and settings. Here is a link to the advanced methods of boot repair, it will require the recovery disc mentioned by BloodPhilia, or borrow a Vista Install disc from someone to repair. Or try the W7 disc you have to repair the boot issue.
