I had windows 7 ultimate running on my machine, I wanted to multiboot with Windows 8 pro . As I started windows 8 pro setup , throughout the process it didn't ask for destination (or drive) to install new window on, it simply goes on & after the completion, I figured out it installed on the c drive on which I had Windows 7.

Did you even have a spare drive or partition for it?

When you hit Install Now on the installer, it will ask if you want to Upgrade or if you want to do a Custom Install, you should've pressed custom install, there you can choose and edit your drives and partitions and also choose where you want to install it

thank you Hamza for the reply.

I do have a spare drive (even Hard disk, which I use to store data only 2TB; Secondary & the one I use to install OS 500gb; Primary).

After hitting Install, it didn't ask much of the setting, it restarts couple of time.

The disk partition I had Win7 installed on was around 82+ GB (c drive), I made another 80+ GB (d drive) for the new win8 OS. [Though 30gb is enough for the OS but I didn't want to be worried for the years to come so I allocated more room anyways]

 

If I can provide any info. which might require, please let me know.

By the way, Before win8 installation, the c drive was 55+gb free out of 82+gb (with programs installed i.e.; around 27gb used).

Now After win8 installation, it still show about 55gb free out of 82gb, which made me thnk that win7 might me recovered. and yes I opted for keeping files while installing the win8. (if this helps !)

Hello Aura. Thanks for your reply.

I attached the screenshot of disk management.

 

there, C, D, E are the (3) drives of the first hard disk, which is of 512 GB. 

and G, H, I are the (3) drives are of Second Hard disk, which is of 2 TB.

 

I especially made D drive for second OS, that is win8, but during setup it didn't ask for installation destination and just installed on the current system drive that is C drive.

And now, when you boot your computer, you just have the option to boot in Windows 8, and not Windows 7, is that right? You could try to use EasyBCD free to create a BCD that will handle both Windows 7 and Windows 8.

I'm currently using windows 8.1 (the OS I installed mistakenly on c drive which is working with no issues), The real question is Can I reinstall (or roll-back) or get to previous state of win7 on my C drive with all the data intact by deleting win8 which is mistakenly installed.

 

I like to install win8 on another drive i.e.; D drive (which is now empty.

You cannot rollback an installation and restore data that was deleted during the process sadly, no. You can try to use free data recovery tools to recover the deleted data, but none of them will guarantee that they can recover everything, if anything at all.

Yes I understand, I have formatted system drive & freshly install win7 (which is on C drive)

 

But here's a ques., I've partitioned 100gb for C drive & 100gb for D drive.

My win7 is installed now in C drive. If I want to install win8 as multiboot, do I need to 'shrink' the C drive to install or I can install on D drive also (i.e;  C drive 100gb for win7 and D Drive 100gb for win8).

 

But when I try to initiate the process of installing 2nd OS, i.e; wind8, it didn't ask to select the drive to install (in this case I want to install win8 in D Drive separately)

ir just starts on installing in C Drive.

What precautions I need to take to do it correctly.

You can keep your current setup. The only precaution you have to take is to pick a "Custom" installation. When you pick that installation mode, it will ask you on which partition you want to install Windows 8. This way, you can select the free 100GB partition and install Windows 8 on it. If you have issues with the BCD after, you can use EasyBCD Free Edition to create a custom BCD that have Windows 7 and Windows 8.
