Windows 7: Deleted System Partition and cannot create another one.

Deleted System Partition and cannot create another one.

Hi guys, i'm having the following annoying problem.
I wanted to format my notebook because it was kinda buggy and stuff, well, as my dvd from windows 7 ultimate x64 is broken, i tried to install using a bootable usb, everything went great but then when i had to format the partition, i deleted the system reserved, and then it won't let me install windows 7 cause it ask for a system reserved partition.

I tried formatting everything using gparted, but it didn't work. I have a 32 x version of win 7 ultimate too, a dvd, and when i run it, it installs whithout problems, but i want the 64 bit, and i only have it on a usb.

is there any way to install it then? It's been three days fighting with it and i can't make it work.
What's worse, I burned two dvds with this official Iso of win 7, but it seems my notebook dvd reader is not working right and it won't boot any of those two dvds... so i'm really out of my mind with this happening lol

Hope you can give me an answer to this problem!
Now i'm making a clean all, as i read that doing this and then going back to the installer would make the system reserved partition appear again, but i'm not sure...

Thanks in advance!

Clear the disk (maybe with cmd) and define an active, primary partition on it. For the OS 50GB should be ample. Then install to that partition. If you want to use cmd (e.g. from the installation disk) those are the commands:

Diskpart
List disk
Select disk n (where n is the number that was given for your disk in List disk)
Clean
Create partition primary size=50000 (parameter is is in MB; = 50GB)
Format fs=ntfs quick
Active
Exit

thanks for the reply, the thing is that i didn't want to create a partition for installing windows, i wanted just one for windows + data, all together. I don't know if it's good or not, but well, would it be recommended then to make a primary partition?

If you want to make just one big partition on the drive, for both windows and data, the command would be:

Create partition primary

Rather than "Create partition primary size=50000"

Ok, let me try, now i saw that if the partition is not formatted, it will automatically create the system reserved... i tried with the flash usb, but it kept asking for the system partition, so i am installing the 32 x from my dvd now, to make the system reserved appear, and then try to install from the usb once again.

Now that i'm going to install 32 x, isn't there a way to "upgrade" to 64 x without making all the same process again? I mean, format partition and install and so...
Thanks for your help!

edit: i forgot, would you recommend to install win 7 on a partition only for this, instead of having all together? and why?

If you move from 32 bit to 64 bit, you must start all over---reinstall Windows and all applications.

Putting Windows 7 and data on separate partitions has several advantages:

C partition is smaller, so image files made of C will be smaller and can be made more quickly.

If C has only Windows on it, you don't have to be worried about backing up your data when reinstalling to C.

Virus and disk scans of C partition will be faster.

Separating data from Windows generally helps simplify and speed up backups and Windows reinstallation.
