Couple of years ago I managed to install XP onto my wife's Acer Aspire One (running Linux at the time) from a USB key. This was the way I did it, and worked fine... 1.Copied XP set up to my hard disk 2.Used Nlite to integrate SP3 3.DPs_BASE.exe to add DP_MassStorage_wnt5_x86-32_901.7z 4.USB_MultiBoot_10 to make the XP installation on USB Had a few issues along the way, which you can have a laugh at here.. http://reboot.pro/8758/page__p__109025#entry109025 Anyway, now is the time to do it again, needless to say I'm running into some issues. Step 1 - copying the i386 folder to my harddrive is fine. Step 2 - integrating SP3 through Nlite is telling me I have a corupt file (not sure which side, XP source or SP3 file - either way, I guess I can skip this part and update after the install). Step 3 - Here's the hard part... When I last did this, it took 30 minutes to unpack DP_MassStorage_wnt5_x86-32_901.7z into my target folder. This time, it only takes around 1.5 minutes. I followed DP_MassStorage_wnt5_x86-32_901.7z to the letter, and the tutorial shows a screen shot of less than 2 minutes. So first question - how long should this really take? Step 4 - USB_MultiBoot_10 seems to work fine, but I see the following... This (to me) looks like the file hasn't been unpacked to the target folder properly? And the size only increases by 7Mb (the original size of DP_MassStorage_wnt5_x86-32_901.7z). I think this is the reason why my install is crashing, (blue screen after the Windows Setup begins). I know there's other tools out there to do this, but I was happy with the USB_MultiBoot_10 method and would like to do the same this time. Any help would be greatly appreciated.
