Windows 7: Hard Drive Management Gone Haywire

Hard Drive Management Gone Haywire

Yesterday, I decided to get rid of the 199MB System Reserved partition in my hard drive setup. I had the 199MB partition at the front, then a 150GB data/system partition, then the rest was unallocated space.
Using MiniTools partition manager software, I deleted the 199MB System Reserved partition (and yes, I re-made the BCD and the MBR), extended the data/system partition to the left to occupy that 199MB, and shrunk the 199MB from the right of the data/system partition, because I wanted to keep it at 150GB. This was all done at a boot-time operation.
When I booted up the computer, looked in the Disk Management, it said that the disk was only 150GB in size. There was only that one partition, and it didn't show the unallocated space.
I messed with it for a while, but when I went into Diskpart and attempted to create a primary partition, it said that there was NO space at all.
Using EaseUS partition manager software (I uninstalled MiniTools because I didn't like the UI), I created a new partition with the unallocated space. It always gave me an error "Updating system information failed", and when I wanted to do anything in Windows' Disk Management, it would give me an error that the information was up-to-date, and refreshing didn't work, so I had to restart. When I restarted, it looked like this [attachment 1]. The unallocated space, approximately 400GB, is no-where to be seen. It actually looks like this [attachment 2].

How can I fix this?
Thanks! Sorry for the long post :P

Always use the Partition Wizard boot disk which is the only manager besides Disk Mgmt which will not fail in countless thousands of operations we've helped with here. Easeus and all others including PW Home version can and will fail with data loss.

PW boot disk will also give the authoritative read on the disk when Disk Mgmt is in error. So I would boot it now to Resize Partition - Video Help.

If there is further discrepancy, I'd run Partition Wizard Partition surface test to check HD condition, followed by Partition Wizard Check File System on each partition.

Thanks Greg, for the advice
I'll try it now, although I was really puzzled by Disk Management's readings
Will report back any issues.

What do I use to burn the software to mah USB?
EDIT: I realized that all of my USB flash drives do not show up in Disk Management or in the Start Menu :P But my USB mouse and keyboard work

Since it's a small ISO file you can rightclick it to Burn or Open with Windows Image Burner. If that's somehow missing install and use ImgBurn to burn an image file.

Do your flash sticks show up in another PC? Do they have a drive letter? Drive Letter - Add, Change, or Remove in Windows 7 - Windows 7 Forums

See if they show up in PW then run Check File System on them which can resolve issues.

Your PC may have some corruption so I'd also run SFC /SCANNOW Command

Okay, here's an update:
In my PC, it will NOT recognize ANY flash drive I plug in (I have 4 different ones). Disk Management doesn't show them either.
Second, I created the PW Boot Drive on my USB using computer 2. I booted it with computer 2. It works fine. (I used Universal USB Installer to burn the ISO). I try it on my problematic computer (manually overriding the selection and manually booting from the USB), and it SKIPS the USB and boots straight to the Windows OS. I try with a Windows install USB I made a long time ago, it works FINE.
Did a CHKDSK last night, it found some bad sectors, but nothing else. I have the log, if you want it.
I'm doing a Startup Repair right now. Will do SFC later.
Also, will System Restore do anything? I have an image I made 3 days ago for some driver issues and BSODs that were resolved here @SevenForums. My only concern is that it will revert the state of the drivers that I modified.

Yes the 3-day-old image would have the corruptions you fixed. system restore may also.
In Device manager, any warning icons?

I'll check Device Manager later, doing System Repair ATM. Also, when I plug in a USB flash drive, it makes the sound that Windows is supposed to when it recognizes a drive. So I guess it's not the flash drive's problem. That is confirmed, cause the flash drive works on my other computer.

It recognizes your Windows 7 installer USB stick in both Explorer and Disk Mgmt?

If so then run Disk Check on the other sticks. If they don't show up in Disk Mgmt, try PW home version.

It doesn't recognize ANY USB sticks in Disk Management and Explorer. Also, I cannot boot from PW USB version. All my USB sticks are functioning perfectly.
PW Home version cannot make changes except for a restart between each one, because it says "Updating system information failed" each time.
:P I've been stuck on the System Repair showing "Attempting Repairs" for 15 minutes now
