Windows 7: Set up Dual Boot w/same Win 7: conflicting instructions

I think that's a left-over from the "old days" of computing, perhaps Extended partitions were the first ever to be created and then Windows decided to use Primaries and Extended still keep the designation " 0 " like the letters " A & B " are left-over from the FDD era.

I'd be really interested in hearing from someone that has a definitive answer myself.

Sorry for the long delay!

Yes, the 2nd OS is also configured as C:

Thanks for keeping me on the right track!

And Gregrocker, thanks for the info on Partition Wizard. I actually had already utilized another post of yours in another thread to download and use that program when I started all this. I burned it to two different DVD's using two different methods and couldn't get either to work. Each method left a slightly different image on the DVD, I forget the details now (too much else to do!). So I read yet another post on this site about using YUMI multiboot installer to boot from USB - and that worked great! I have to go thank Jumanji for that one.

I still have way too much work ahead of me, so I'm posting this as Solved and moving on. But this site is a godsend, and I'll be here reading (and posting) on other subjects.

My thanks to you both - to all of you who contribute so much. I'm grateful.

Use WIndows Image BUrner or ImgBurn to burn PW CD ISO to CD, not DVD. No one else reports problems using those burners.

You could easily Resize the Logical container to the right into the Unallocated space with PW CD.

Then you can resize C into the space to the right as much as you want, even saving space for more storage if you desire.

Thanks for the advice. I did use the Windows Image Burner, but didn't have any CD's on hand (and may never again) so thought that DVD would be the equal. But I'm really happy with the USB solution, I'll probably go with USB from here on out - except possibly for a Windows Repair Disc.

But I will definitely be using PW to rearrange partitions in the future. Good video!

For repairs you can boot the Win7 installer System Recovery Options .
Troubleshooting Windows 7 Failure to Boot

You can write the Win7 installer to flash stick and still load other files as long as you leave the seven installer folders in the root of the stick when you intend to boot it - I keep them in their own folder at other times. To write the stick use Universal USB Installer with Win7 in dropdown menu.
