I've lost count how many times that trips up the Windows installer.
A blank drive with no partitions gives me the best install.
--> FIRST, must decide if you want that drive and what is there "ALL GONE." If so, we are ready.
There are 2 ways I do this. The Microsoft way and another way. Here we go.
1. STEP 9 of http://www.blackviper.com/Articles/OS/Install_7/install_7a.htm shows where we can remove the old partitions, create one new one and carry on with a CLEAN INSTALL.
2. The other option I use a lot is GPARTED. Found with google I can boot that CD and delete the old partitions there. Not hard to use.
Hope this helps.
I am going to install WIN7 from a full WIN7 disk. Would it be wise to reformat my drive to totally wipe out Vista to be sure WIN 7 cleanly installs? Also, part of my C: drive is partitioned into a D: drive Dell restore partition. Do I need to remove this soon-to-be-useless partition prior to WIN7 install?
