804425 2009-08-26 06:03:00 Currently I have dual boot on my laptop with XP on C partition and Windows 7 on D partition.

Is it possible to erase the C partition and make 7 as the OS without reformatting the hd and installing 7 again?

804426 2009-08-26 06:11:00 Not easily.

You can however resize the disks so the primary partition is only 10MB or so, hide it, then have Win7 fill up the other?

804427 2009-08-26 08:32:00 Couldn't you just delete the WinXP partition, cause you would be using the W7 bootloader, and resize the win7 partition to maximum size? Netsukeninja (13296)
804428 2009-08-26 08:36:00 However parts of the bootloader are most probably stored on the first primary partition which XP will be on. Removing that means you have to do a Win7 "repair".

Not a biggy, but yeah...

804429 2009-08-26 08:43:00 I assume you installed XP first.

Here are the steps:

1. Delete XP partition. You will need to do this from Gparted (sourceforge.net) or from a Vista/XP/7 boot cd as disk management in 7 will not allow you to.

2. NTLR error will pop up when you boot. Thats normal. Boot from your Windows 7 DVD, then select repair. Run start up repair.

3. Using Gparted, expand the 7 partition.

4. You may need to set the 7 partition as active again, although it should already be.

Its pretty simple...

804432 2009-08-26 11:27:00 Can be done, but just remember that the only Current public Version of W7 is the RC, and according to MS you cant upgrade from RC to the GA (General Availability) so you will need to do a full install any way.

And even if there's a work around by rights you will have to use the Ultimate version

As of May 4th :
Please note: All users of the Windows 7 Release Candidate (including Windows Vista users who have upgraded to the Release Candidate) must do a clean installation of Windows 7 RTM. Please keep this is mind as you consider downloading the Release Candidate as opposed to waiting for the general availability release.

It is possible to upgrade from RC to RTM with a minor tweak.

I've tried it, and it works.

804434 2009-08-26 11:36:00 Personally I wouldn't trust any upgrade like that.

Hell it only takes around 30 minutes to install (all versions).
