xp to windows 7 rc

You might need to do a Fresh install instead of an update. Fresh installs work better (complete operating system disk(s)) than updates from one operating system to another.

Into a clean hard drive.

I've got Windows XP Pro co-existing quite happily alongside Windows 7 RC - but each installation is on a separate hard drive.

In fact, you cannot even install Windows 7 RC 'over the top' of Windows 7 Beta. According to Microsoft:

[i]If you are running Windows 7 Beta you'll need to back up your data (preferably on an external device) and then do a clean install of the Windows 7 Release Candidate. After installing Windows 7, you will need to reinstall applications and restore your files.[/i]

So if that's the advice regarding Windows 7 Beta, I'd think it would be prudent to follow the same advice for XP Pro as well.

I would STRONGLY advise against installing the Windows 7 RC or any other "test" / "beta" software over your working released software drive.

First of all, you will find it hard to go back to XP should you have problems with 7. Also, and even more important, is that all Microsoft bate and release candidate software have built in expiration dates.

I strongly recommend that you install Windows 7 on a clean separate hard drive and switch drives when you want to change from Windows 7 to XP.

As a side note, have you checked your hardware for Windows 7 compatibility?

If you know your system can run Vista, it should be able to handle Windows 7. If any hardware is not supported by Vista, it will not work with Windows 7 either.

Microsoft has released a beta version of a Windows 7 upgrade advisor. This software looks at your hardware to verify it can support Windows 7.

I did a clean of the Beta but an upgrade to the RC.

Under sources edit cversion.ini and set the version number to something really low.

I only did it Beta to RC, but maybe it will work with RC.

Hi Balge,
Thanks for your reply, even as you mention with the compatibility tool passed and doing a clean installation as M$ suggests, I'm still stuck, thanks for the link but that was the first place I looked they only specify a Pc with a DVD burner...found some websites that mention setting the burner to the slowest setting, but even then nothing... will keep looking

I get to the Setup is starting...then a window pups up with:
A requiered CD/DVD drive device driver is missing. If you have a driver floppy disk, CD, DVD or USB flash drive, please insert it now. NOTE: If the windows installation media is in the CD/DVD drive, you can safely remove it for this step.

[Browse] [Ok] [Cancel]

and that is it, any suggestions? thanks!

Once the setup started and starts to copy files etc...suddenly a windows pops up with: Windows cannot install requiered files.The file may be corrupted or missing. Make sure all files required for installation are available, and restart the installation. Error code 0x8070017

Which in turn researching this code lead me to a bad burn or needed to burn the ISO at a slower speed. What do you think?

You cannot upgrade XP to Win7. A clean install is the only option.

So far the Win7 RC has been stable and I haven't experienced any problems (using 64 bit version). But I do agree that you should not use pre release software for crtiical work.

I take it you ARE installing Windows 7 using the same DVD drive that was used to burn the ISO to disc, aren't you ?

The only other thing I can suggest (although it's a real pain in the arse) is that you might have a glitchy download. You could always try downloading again (or find a mate with a download and try that - all you need is a different key from the one your mate has, and you can get another key just by logging into the download site).
