thanks for that , another little matter popped up yesterday , i ran windows upgrade advisor through the PC just to make sure it would be ok to run win7 in .
the result showed no problems as far as the machine is concerned but it did possibly present me with a problem, it only accounted for one drive , the " c drive " ( 164.5 GB free of 186 GB available , so it has the XP on it , made no mention of the " d drive at all ) then it suggested i back up all of this stuff, do a custom instal of the win7 O/S , then re-instal the old XP files that i have backed up.
this is all ok but it said that i need a 32 bit version of win7, my question is , is this because these old XP files that i have backed up and then re-installed will not run in any 64 bit version i win7 i instal in the machine , or to put it another way, if i delete EVERYTHING fron the ' c drive " can i then use a 64 bit version of win7 , i do not care about any of the files that are at present in this XP PRO P/C , they can all GO.
or if i instal the win7 O/S on my " d drive " ( 465 GB free of 465 GB ) could this be a 64 bit version ? even if i left the XP on the " c drive " , just to repeat i am quite happy to wipe everything from the P/C , both drives , more important to me that i use the 64 bit version of win7 .
i have another XP laptop i can use anything i back up from the c drive in the desktop, thanks again for all of the advice, donar
