Impossible to restart - wrong use of my7bootloader

Hello,

I have a Sony Vaio VGN laptop, and just upgraded to a tower . I asked a friend how to prepare a bootable usb key with windows 7 64 bits for this new PC. Unfortunately I think he mistook and, with the ISO file, he provided me a software: "my 7 bootloader ultimate"; which I thought was the boot creator (I'm not really good at this... )

So I naively ran the my 7 bootlader on my laptop... I choosed "Activate Windows 7 (emulation SLIC)"
The only clever thing I did: I didn't restart at this time. And fortunately, thanks to this forum I understood how to really do a bootable usb key, and even managed to do a 64bit boot from my W7 32bit.

And now I just restarted the laptop:
-"VAIO screen" (a few seconds)
-Black screen, with only a small dash...
-Nothing more happens... I'm really in a bad situation.

I hope someone can help me on this, thanks in advance

Hi,

I'm writing now from my other computer.
but the laptop isunable to start at all. So no possibilty to run this tool.
I just have this black screen with white dash... and I can't write anything like if it was a command screen.

I can enter the bios only

Thanks for your answer

I tried to press F8 during start but it doesn't work

you mean crash all and re install w7 ??
No way to get back files from the HDD in your opinion?

OK so I guess to boot on the DVD player.

Now i have to choose which boot... what do you think?:

-The laptop was given with VISTA and I think an upgrade DVD for W7, so I have a DVD1 where I find some folders "Vista" and "W7"; I have also another DVD2 "upgrade to W7"

-A long time ago I also did the VAIO "recovery DVDs (3 of them)

Also, Maybe My7bootlader may have changed the registration number..?

Thanks
