Windows 10: Deleted Windows 11 Partition on Another Drive, but my Boot Drive Won't Load Now.

I'm going to take the time to describe this issue in detail so please bear with me.I recently upgraded from a 500gb SATA SSD to a 2tb m.2 drive. I used software to clone the drive, and all of its partitions, to the new drive, as well as expand the main "windows" partition. This all went completely fine, and I've been booting completely fine since then, but my BIOS doesn't let me set the m.2 as my main boot drive I have 3 different Windows drives and it automatically chose the SATA SSD to boot from.

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that

 

2 of my internal hard drives, not been reconized!!

In that case do what Blue-Knight suggested and delete the partitions from the Windows install disk. Leave just the two drives you want to format plugged in and boot to the Windows install disk. When you get to the disk manager delete the partitions so the drives only show unpartitioned space.

Once you do that turn off the computer and boot into Windows. Now you can partition and format the blank drives through disk manager or using diskpart.

 

Partition or multiple hard drives?

As the title suggests. Is it worth installing say a 36GB drive for the OS soley or partitioning an existing larger drive with either 2 or more partitions? I am currently running Vista 32bit and want to try out 64bit and am sick of reformatting the whole drive. Any suggestions?
