Acer Aspire 7738G partition dissapear

[GoldSpot]

I got a problem on Acer Aspire 7738G . i have a really weird problem in it . it is with windows vista 32 bit . i try to create another partition by shrinking C:evry thing gone well i got it . but this morning when i restart it the partition was lost couldn't do any thing. Disk management can see the partition.what have gone wrong . i did the process again but no solution after reboot it disperse Why does that newly created partition dissapear after reboot?
Thanks in advance.

Some ACER models need to have the D2D recovery system enabled in the Bios. Enter the bios by pressing F2 when booting and look for this option. or you can use the Acer Aspire Recovery Partition .

You need to look at the Disk Management you will see hidden partition tagged as EISA . after you shrink C: the first reboot windows hides the newly created partition converting it to EISA.you need to create RECOVERY DISCS open your case take your hard drive and use this in another pc . INSTALLED Paragon Partition Manager Professional 9.0 and you need to eras all the partitions INCLUDING the hidden once . now make partition using the software formatted it to NTFS and disable BIOS D2d recovery before installing windows .
