Windows 7: Can't Install W7 over XP... what am I doing wrong?

Can't Install W7 over XP... what am I doing wrong?

I currently have XP on my machine. I've copied the files I need saved, and want to install Windows 7 new. I insert the disc, and I'm told to reboot the PC, and then choose custom install. However, I leave the disc in the DVD drive, restart the machine, and the disc never comes up. I'm brought right back to the log-in for XP.

What am I doing wrong?

Do you have yor Bios setup, set to boot from CD/DVD first, the HD ?

Yes. I went into Bios and made sure it was set-up that way, and it was. Still not reading the disc.

Is this a retail Windows 7 DVD or one that was made from a .iso file?

Retail. Got the pretty box and everything. Just double checked the Advanced BIOS Features:

First boot device: CDROM
Second boot device: Hard Disk
Third boot device: Removable

The disc worked before when there was no OS already installed, but now it's giving me this trouble. Any thoughts?

Sometimes you can get a Boot Menu screen during boot-up if you tap the F8 or F10 keys

Okay, I'll try that. Hitting the delete key brings me up to my BIOS screen, but I'll try F8 and F10.

Thanks, DocBrown! Hitting F8 brought up the Advanced Boot Options screen. From there, I chose 'Start Windows Normally', and it read the disc.

Problem solved!

Good job, Just ask more questions if you have any problems with anything else.

It's a DVD, so you're not using the CD-ROM drive set first to boot.

I would wipe the HD before install to overwrite old or infected code: SSD / HDD : Optimize for Windows Reinstallation
