*The solution*
To close this subject i have found the solution, the problem is in the partitions. The computer has a special partition related to its use on a network probably.
Use fdisk and select option 3 to delete partitions, now try all options until you delete your partitions. i used option 3.
once that is deleted select option one to assign logical drives, then select option one again to set the primary partition. before making a decision read the note*
If you want one drive with 100% space on it type 100%(use the percent sign)
If you want to partition your hard disk into multiple drives choose a percentage or megabytes (other drives will be assigned later, remember to use the percent % sign)
*(note that it makes sense to split your hard disk into an operating system drive and an extra storage drive so you dont lose work when the computer gets messed up again and you have to reinstall. the acer laptop i setup has 9gb hard drive i used a 33% for the primary)
When you have made your decision and you are back at the main menu choose option 2 and set your primary parition to active(press 1 then press enter)
If you set your primary partition to 100% skip to the ** below
If you didn't that is, for multiple partitions read on...
now select option one,(we want to set up the extra drives).
select option 2 we want to set up our extended partition to contain the extra drives
If you are asked to use the maximum available size press y
if not choose the maximum value in mb available or choose whatever percentage is left from the primary drive.
you may be sent automaticaly afterwards to define your logical drives
if not(from the initial screen press 1, then 3)
before you continue decide how many drives you want,
Now set the first drive by choosing its size in % or mb, (dont include mb, choose 100% to create only one extra drive giving you 2 drives on the hard disk, like i did), press enter to set this drive (D:?)
press enter and choose your second and so on untill you get a message telling you that you have filled the partition like "
All available space in the extended dos partition is assigned to logical drives".
press escape to continue
** your hard drive is now partitioned the way you wanted, it should start from drive C:, I dont know what drive letter you CD drive will assume as mine was on R: for some reason.
Now you can format your drive/s type "format C: /fs:NTFS" you can choose a different file system or not include it, format all drives, i recomend specifying a file system, you can choose "format /?" for more help
once you finish that i recomend using scandisk before installing an OS.
Good Luck.
