Windows 7: help: windows 7 won't boot after changing active partit

help: win7 won't boot after changing active partition

i have three partitions. P1) 1 logical with windows 7 RC, P2) 1 primary and system, (not clean install) with windows 7 7600, and P3) 1 primary with windows 7 7600, (formatted partition before installed).

my problem happend when i tried to set the active partition from "P2" to "P3" using EASEUS. I used "P1" while doing this. after restarting, my machine won't boot. It shows the manufacturer logo, and then followed by a black screen with a flashing cursor on the upper left corner, doing nothing. i let this stand for ten mins but, still, nothing happens. is this normal? i also noticed the manufacturer logo showing a little longer than usual.

after 10mins, i decided to restart my machine but the same thing happens. i managed to make a repair disc before this happen. so, i boot in to the repair disc. i tried startup repair but nothing changed. i tried setting the active partition again using CMD. i also tried system restore to "P1" which i used to open EASEUS. and it also failed.

any ideas what went wrong? and how i can fix it? thanks guys!

Boot the 7 dvd/recovery disc to the system recovery options and select command prompt.

Type the following at the prompt: ( press enter after each command)

( replace vol 2 below with the volume number you wish to mark Active )


X:\sources>DISKPART

DISKPART> SEL DISK 0

Disk 0 is now the selected disk.

DISKPART> DETAIL DISK



Volume ### Ltr Label Fs Type Size Status Info
---------- --- ----------- ----- ---------- ------- --------- --------
Volume 1 C New Volume NTFS Partition 30 GB Healthy System
Volume 2 D New Volume NTFS Partition 25 GB Healthy
Volume 3 E 7000 x86 NTFS Partition 23 GB Healthy
Volume 4 G Data Logica NTFS Partition 40 GB Healthy
Volume 5 H Backup Logi NTFS Partition 30 GB Healthy

DISKPART> SEL VOL 2

Volume 2 is the selected volume.

DISKPART> ACT

DISKPART> EXI

close cmd prompt.

Try restarting or startup repair after that.

Download the recovery disk from here: Download Windows 7 System Recovery Discs — The NeoSmart Files

Write it to USB flash stick using this: USB Windows 7 Installation Key Drive - Create

Boot USB flash stick using one-time BIOS boot menu key. It may be listed under Hard Drives.
