Dual Boot Windows 10 with Windows 7 or Windows 8

Well again the idea is to primarily run Windows 7 say until we are sure that Windows 10 will properly support things we require, but still have Windows 10 testing abilities.

This approach would not only not require a separate box that remains Windows 10, but also continually tests the upgrade process- which will be a good indicator if suddenly problems arise.

If you have the hard drive space, why don't you just dual boot? I'm dual booting and have upgraded Windows 8.1 on both laptops to Windows 10 while leaving the Windows 10 partitions intact and still activated.

Legally by the EULA, you are not suppose to have the 8.1 installed and activated with the 8.1 key you upgraded to the free Windows 10 with unless you uninstall 10 first, or use a different key to activate 8.1 with.

I don't, Shawn!

I had Windows 8.1 on one partition and Windows 10 TP on another. When Windows 10 launched, I upgraded the Windows 8.1 partition to Windows 10 and left the Windows 10 partition intact.

Microsoft has said that we can have both a "regular" installation of Windows 10 and a Technical Preview installation of Windows 10 which is what I plan on doing.

Not my style to "get around" the intended license terms.

In that case it's fine, since one is Insider, and the other is a legal upgrade. :)

I thought you upgraded to 10, then reinstalled 8.1 with the same key. LOL

Ohhhhhhhhh, nooooooooooo, not moi! I'd be the first one they'd ketch! :)

So how about a dual boot with Vista64? I know, it's old but what the hell, it's been great. I missed the deadline for the free upgrade with Win7 (had a copy I could have used) but i bought an oem Win10 pro and I have a never used 1tb velociraptor.

In about a month I'm going to bild a new beast, but for now I just want to plop 10 on this old machine.

Can I do it? I'm formatting the new HDD now, should be done in about 4 hours lol, and I plan on using the new drive for the WIn10.

Same steps as above for Win7/8?

I also have a 120 GB SSD I just bought that I can use for the Win10, but I'm getting too many HDD's in the case already...... should I use it anyway?

It's been a long time Brink. Glad you to see you are doing well. (WAY back when Vista was new lol, and this was the VistaX64 site)
