Windows 7: Can't install win7 x64

Can't install win7 x64

Hello,

This is the story so far:

My pc came together with windows vista home premium but because i didn't like it, i installed win7. Everything worked just fine. I reinstalled it around 15 times to experiment with things like making it unattended and such and still, everything worked just fine. When i had enough of windows 7 and wanted to downgrade back to windows xp, i thought i needed to completely erase my disk which i did using the windows 7 setup. After i inserted my windows xp disc, it never recognized my hd so i tried to go back to Windows 7. When i came to the step where to choose wich hd you want to use to install Windows 7 to it gave the error: Setup was unable to create a new system partition or locate an existing system partition.

These are the things i tried to fix it:

- Looked in my motherboard to change ACPI to IDE No such option exists.
- Tried several options using diskpart like formating it in ntfs, assigning the letter A, making it the first volume and disk etc...
- Changing the boot order to boot my hd first.
- Installing Vista again but gave somewhat the same error.

These are some facts:

- Ubuntu installed just fine, I'm currently using it.
- The setup recognized my hd.
- I have no extra disks available.
- My pc came with a hidden partition named PQSERVICE or something of 14.65 GB which i deleted. Windows 7 still installed fine after that.
- I could have forgotten some things i tried to fix it.
- I install windows 7 from an usb formatted as ntfs of 4 GB
- I have no idea how to even install things in ubuntu so no lead there.
- I am not very techy in pc's but i know most of it so i'm willing to experiment.

So long things short:

The problem started right after i used the format hd utility in the Windows 7 setup.

I am very sorry about my crappy English, i hope you could understand most of it.

If someone knows how to fix this or even has an idea to fix it, please i beg you tell me i really miss my pc.

Here are most specs if it helps:

@richc46 I already did this with diskpart, even creating multiple partition under different sorts of fs (Fat32, ntfs) but still the same error.
@Liquidsnak I used the build in format utility from the windows 7 setup.

Hello steerty, welcome to Seven Forums!



No the 'clean' argument is not at all the same as the 'clean all', the 'clean' just over-writes the Hard Disk Drive (HDD) format data (no better than a regular format) and the 'clean all' over-writes all the data on the entire HDD with zeroes.
