Cannot boot, critical problem

thanks mark would try your suggestion(avira) and do malwarebytes remove threats or just creates a log

Yes, Malwarebytes free version will remove threats and create a log. You just can't run it as an active anti virus the free version is just for doing scans.

Oh, bye the way, love the picture, lol.

would malwarebytes clash with antivirus program ?

When you use Malwarebytes for running a scan disable any other AV progs. The rest of the time you can leave it on your PC without any problems. The free version only runs scans, it is not an active anti virus.

hey mark i had run the windows 7 upgrade advisor, and yes i can run it smoothly. is there any way to dual boot windows xp and 7

Indeed there is and here is an excellent guide to get you through it.

http://www.sevenforums.com/tutorials/8057-dual-boot-installation-windows-7-xp.html

actually i already checked those forums, my only problem is with partition

now how can i boot into command prompt from the system recovery options screen if os is not installed

That is explained in the guide, isn't it?

You could use Gparted if you have no choice:

http://sourceforge.net/projects/gparted/files/gparted/gparted-0.7.0/

You can't, you have to boot from the windows disc.

o.k i understood , you know a silly doubt just flashing in my mind is creating a separate partition necessary for dual booting or i could just install on a drive which is empty(D drive) in such case would the data be wiped out ??

Yes you can install on a seperate drive, that is also explained in the guide, perhaps you should read through it and then ask what ever else you need to know. If you install on the same drive you do need a seperate partition for each operating system.

I don't understand what you are asking here. If the drive is empty there is no data to wipe out. If it does have data on it and there is sufficient free space for the operating system then you can create a new partition for the operating system to go on within the free space. If you install it on a partition or drive that contains data the data will be wiped out.

sorry my fault for no proper explanation , i created a new partiton and named it windows 7. now if i perform an install of windows 7 would it wipe the whole hard disk or just the partition in which i am installing it ? i know i asked this question more than once but the data is very essential to me

The install will only format the partition you choose to install it on. Choose carefully.

o.k , well i ordered windows7 ultimate 32bit today at a local electronics store

OK, hope it all goes well, any more questions just drop in a post.

bought windows 7, successfully installed it by creating a new partition in my pc. man its pure awesome

Yes it is a good OS. Glad to here you are up and running again.
