now, how I can reinstall the windows?

Thanks,

Sylphan

Have you been to your disk manager yet? And reassign the drive letter there.

I would personally reformat the drives using a secondary computer. Might be faster.

If you have a valid 25 character Product Key and a Windows installation disk that matches the Product Key, disconnect all but one hard drive and reinstall.

Then activate with the Product Key.

The new installation will be drive C.

Then reconnect the other hard drives.

DON'T reconnect the other drives until the installation is FINISHED.


Reboot after you complete the installation with only 1 drive attached.

Then look in Windows Disk Management and post a screenshot.

All of this with ONLY 1 drive connected.

Worry about the other drives later.

I reconnect it after finished all installation, installing driver, & some essential program... (7zip, Foxit, LibreOffice)
then I shutdown my PC & reconnect the rest hard drive, the hard drive letter messed again... windows refuses to boot

Okay then, I'll do it again & post screenshot of my Windows Disk Management, but I'm working in office now, so maybe latter after I'm go home

sylphan,

Simple:

  1. Disconnect all drives except for the one where you want to install Win 7.
  2. Wipe the hard disk clean using diskpart.
  3. Install win 7.

==========================
now here's how to wipe that hard disk clean using your Win 7 DVD.
1. boot up your Win 7 DVD
2. at the very first dialog, hit SHIFT + F!0 key combo.
that will get you to a command prompt, that looks like this:
X:>
now enter these commands:

USE THE DISKPART PROGRAM TO “CLEAN” THE HARD DISK
Type the commands shown, hitting the Enter key after each.

Do not proceed to the next command until the current command is finished.

· DISKPART (the command prompt will change to DISKPART>)
· LIST DISK (this will list the disks present)
· SELECT DISK 0 (assuming disk zero is the desired hard disk)
· DETAIL DISK (this will show you info regarding the disk you selected)
· CLEAN ALL (this is the command to write zeros to entire disk)
This can take half a day for a 2 Terabyte disk.
· EXIT(this will exit you from the DiskPart program)
· EXIT(this will exit you back to the Windows 7 install program)

Thanks for reply,

Clean hard disk... formatting? the Hard drive needed to be cleaned using diskpart is just an OS drive isn't? the problem lies when I re-connect the rest hard drive... the drive letter will be messed up... but I'll try it latter....

You need to post that disk management snapshot.

For god's sake, stay away from dynamic drives. No home user system needs such or can benefit such but they durn well can get more than their far share of problems.

No dynamic disks unless you want problems.

I don't know the problem lies, but I'm afraid to reattach the rest...

No dynamic disks unless you want problems.

Well, I made the dynamic disk long time ago, when the drive was OS drive, partitioned, I want to remove partition without removing the data, windows suggested to make dynamic, and I click ok.... I admit I made a mistake...so how I can access the data without reformatting it? or better if I made new thread for this?

Since I never mess around with dynamic disks, than any recommendations I would make would not be from first-hand experience.

I can mouth things others have said but I'm not comfortable with that.

there is no error in disk management.

Make your life easy and straight-forward. Forget dynamic disks which have no place in a standalone system.

Dynamic disks are designed for other environments and even there they are only an emergency measure.
