Question

Q: Error code 0x80070490 - 'need boot disk partition of 686Mb on boot disk'.

Using a Pentium 4 PC with plenty of RAM and spare disk space to upgrade from Windows XP to 7. No idea how to create this space for the temporary installation files

Answer

A:

I'm actually upgrading from XP, and I'm not even getting as far as Accept License agreement before I get the error message
Well, you can't do an in place upgrade from Windows XP, so its best you boot from the Windows 7 DVD and do a Custom (Clean Install):
