Win 10 boots...

I can't answer to the speed of Win-8 booting. I tried the Win-8 preview and went back to Win-7 after a month. They say that Win-8.1 is a lot better than Win-8 was.
My Win-10 TP is working well ATM.

 

Win 10 upgrade on a Win 7 and Win 8.1 multi boot system

I have a system that multi boots into win 7 or win 8.1. Why ? Well win 7 is 32 bit and win 8.1 is 64 bit and I was going to slowly set up the 8.1 system to mirror the programs on the 32 bit Win 7 install as there is no automatic 32 to 64 bit migration path.
Both have genuine Win 7 and Win 8.1 licences. I delayed the 8.1 upgrade as Win 10 was coming.

Can I upgrade the Win 8.1 install to win 10 and keep the multi boot options as Win 7 and Win 10 or will the win 10 upgrade kill the current multi boot configuration.

Any advice appreciated

 

Uninstall Win 7 upgrade

I recently upgraded one of my Xp rigs to Win 7, and i did a clean install [custom install > full] but gave me an option to install Win 7 on my secondary HDD which i did, but now i just want to go back XP since i don't really need win 7 on that rig. Weird thing is that when i boot [from my XP HDD, as selected by BIOS] I get the option to choose either OS, even though the Win 7 OS is on the other HDD.

Quick question:
How could I uninstall Win 7 from my secondary HDD, without affecting my primary HDD, since [i think] some of the Boot files of Win 7 are on my Primary [XP] HDD.
