unable to boot my lappy(acer)

[bluenetra]

hello all,

somehow my hard disk partition became dynamic. i formatted system and insttaled windows 7 ultimate in the dynamic disk partition.

from then onwards system is not booting. only black screen with cursor on the upper left corner of the black screen.

if i am not wrong windows 7 cannot boot with dynamic disk. i will have to go to the disk management and after conversion of dynamic disk to basic disk with deleting all the volumes (data). it is possible to boot with windows 7.

but system is not booting...not opening..so i cannot go to disk management.

hrad disk is showing some partitions with system reserved.

except system reserved all the partitions are shwoing dynamic.

and in only one partition formatting option and installing OS option is coming while i booting system with OS DVD.

reinstalltion through OS DVD is possble by booting through OS DVD. but in advanced option repartition option is not coming.

the one partition in which i installed OS previously, only in that formatting option is coming.
in other partition neither formating option is coming nor extend.
tried to format or delete thru diskpart but was of no help.


tried partition master bootable usb but non of the tools were active(absent). right clicked on disk - shows: invalid MBR signature.

i'm completely disappointed.

tried to install partition wizard as mentioned in other forums i've seen but that too not properly installed(boot NTLDR missing).

pls. show me a definite way out.

thanks in advance.

Do you have any data on the HDD that needs saving? If so, remove the HDD, mount it as an external drive on another system (use a HDD dock for that) and transfer the data in question.
Do you have a system restore of that particular laptop on disks or partitions anywhere? If you plan to do a format you'll need that. Alternatively, you can do a fresh OS install, but make sure you get the drivers and utilities handy from the manufacturer's website.

If/when ready to proceed, download and burn a bootable copy of Killdisk and perform a full wipe of the HDD or partition that you will put the OS on. If you got this far and have questions about this process, hit us back before you do something that you're not sure of.
