So you popped the windows install, and setup OS dvd into the Cd or dvd drive of the system.
It got to the windows install part of the setup where it asked you where, or what drive you wished to install windows to.
And displayed the Hard disk drive in the main windows of drives detected.
Yes?
First question to you is the drive, or was the drive you fitted completely new, bought to use with the system build?
If the answer is yes then good.
When you get an error from the part of windows where it gets to 99% of windows expanding files there are two resons why it fails just before reaching 100%, and the installing the expanded files of the windows setup to the drive you selected for it to be installed to Hudpithicus.
The first is before you start the install procedure make sure that in the bios of the motherboard that for Sata devices the mode of Ahci is selected and not Sata
Once you change the mode to Ahci, make sure you save the changes made in the bios before you exit it.
ok.
Now back to the point where on the windows install and set up it asks you to select a drive to install windows to.
Hi light the drive with a left click of the mouse.
Instead of clicking next.
Click on drive options advanced.
Format the drive first choosing Ntfs as the formatting of the drive.
Once done click on next.
The windows Install set up should start.
The expanding of the files should complete to 100%
The install or expanding of the windows files halts at 99% because the interface mode in most cases set for the hard drive in the bios is set to Sata mode, and windows cannot see the drive if set to Sata mode.
By setting it to Ahci mode for the sata ports in the bios. the drive is then seen by windows when it reaches 99% to 100% of expanding the install files ready for the os to be installed on the drive you selected.
