Windows 7: After first reboot, black screen with scattered alt characters

31 Oct 2012   #1

Windows 7 Ultimate x64
After first reboot, black screen with scattered alt characters


Laptop: Toshiba satellite C660 12 t

It is the first time I encountered such a strange problem.
I simply used "Windows 7 USB/DVD" to burn ISO Windows 7 (64 bit/ 32 bit - Both versions contained in the same ISO file) to a DVD disc and to a USB Flash.

Before installation, I used "MiniTool® Partition Wizard" ISO bootable version (I burned it to CD), And format all drives (So, there is no OS installed after formatting).
I format all drives to NFTS format, I set one drive as primary and set it active. So there is no problem with formatting. My computer now is clear.

I started installing Windows from the USB Flash, It it started normally, and go through the steps up to the window titled "Install Windows" which contains this Text:
Installing Windows
That's all the information we need right now. Your computer will restart several times during installation

Copying Windows files
Expanding Windows files
Installing features
installing updates
Completing installation


This Window completed successfully, and prepared to reboot.

After reboot it displays a black screen with scattered alt characters. the characters has no specific order. A blinking cursor after the last line.
Just reference to alt charachters: 1, 2

That black screen (with characters) remain without any change, I wait for 15 minutes but no thing happened, I press many keys but no response even Alt+Ctrl+Delete for reboot.

I tried booting and installing it again but from the DVD disc, the same scenario happened.

(Edit) Update:
It seems that after the first reboot the screen shown is the same as the screen when choosing
HDD/SSD Toshiba MK3265GSXW (instead of booting from USB or DVD)

Actually I don't know what HDD/SSD Toshiba MK3265GSXW means.

Thanks :)
