Specs: WIN7, 4GB
Hello guys,

I need your help here with my win 7 installation. here is the story:

I was using win7 and it was running smoothly and fast. I had C:, D: & E: drives on my hard disk.

I used a software called: Partition_Wizard_Professional_Edition_v5.2 to delete my D drive and extend the E. also I delete and 100MB unallocated space and added it to C(dunno why, just didn't like it to be there).

now after restarting and doing the chnages on my hard disk the computer isn't booting. I inserted the Win7 DVD and tried to format and re-install but it's going extremly slow!!!.

I burned my Win7 on usb stick and tried it again but still the same. I got WIN XP and tried it. it took me 5 hours to install it and when I use it, it's so damn slow as well.

I installed linux and it was running normally with no issues. I wipped my whole hard drive and tried again but still the same issue.

I googled it and I found some people with same issue. but they solved by disabling anything related to floppy dirve. I tried it but it didn't work for me. also something else about changing the CPU from compatibility mode to normal(I don't know how to do that).

so please help if you have solution or suggestion about my issue.

here is my PC spec's:

That 100MB was a necessary part of Win7. Obviously you shouldn't have wiped it out. Read the 2 responses in green:


As for why your system is running so slowly now, it's difficult to say. You didn't provide enough info. You need to completely wipe out all partitioning, create new partitions, format as NTFS (full), then reinstall Windows. Since your system appears to have a SATA hard drive, I'm curious on how you got WinXP to install?

You do know that Windows 7 can expand and shrink drives without any extra software?

I'd try a reload of the OS. If it seems way slow then I'd test it. Might start at memory diagnostics and then move to hard drive diags.

Be sure that your amount of ram is really being shown. Say you have 2 gig and now it only shows 1 gig.

I didn't know the 100MB was necessary for my WIN 7.

I deleted all partiions and wipped the whole hard disk created new NTFS partition but still the same. what other info do you need? I will try to make a video and upload it to show you what's going on.

I did know that. but I used the partion wizard pro cuz I wasn't able to delete the 100MB part.

memory and hard drive diagnose gave me 0 error (Memtes86 & HD Tune were used for that) but still the same.
I have 4gig and it shows 4 gig of ram.

I have SATA hard drive but when I go to BIOS it shows IDE not SATA. and also WTH is PATA? it was there when I entered the BIOS.

I try to record it and show you.

In some systems you can select how a sata drive is "viewed" buy the bios/os.

If you only want to run Windows 7 you may be able to set it to sata or some term that is for sata. See owners manual for options.

That should not have changed by any reload of OS.

There are plenty of web pages on how to remove or not install that small partition at install time. Seems to be only an added feature, I have never heard of any speed issues related to that.

Can't say why I would ever try to delete it. Not much in the scope of a gig drive.

The Win 7 install should create the 100 MB partition as long as it has enough space and primary partitions available. Best to start with an empty drive and use the advance setup.

Reset to SATA.
Use install disk to do the initial partitioning, go to Custom>Partition/Format. From there make sure all space is unallocated or else delete anything and reallocate JUST the ONE partition you will install Windows 7 on (use disk manager later to continue the partitioning) and in this case do a FULL Format (may take hours though depending on the partition size) and then continue with the install. Once Windows 7 is loaded and you load the drivers then go to disk manager to make any other partitions you need and format them.

You have to be a little bit crazy to keep you from going insane.

how do I reset to SATA?

I solved the problem of WIN 7 installtion is very slow. I went again to BIOS and there was an option says: PATA/SATA Controller: ENABLE/DISABLE.

well it was enabled. I disabled it and my computer is back to run smoothly and fast just like before. I will do the partioning tip u tol me about cuz someone else told me to the same. Thanks!.

I mentioned my full PC spec's in my first post. you can check it out.

but I don't really get it. my hard drive is SATA. why should I disable the SATA controller? and even when I check on device manger, it's showing IDE not SATA.

Yes, we do understand.

If you are happy then leave it alone.
