Windows 7: I cannot install windows 7 RC

[SOLVED]I cannot install windows 7 RC

Hi all you guyz!

Now I've tried to install windows 7 RC (7100.0.090421-1700) on my acer aspire 5920G for the last 4 days, i have tried burning cd, making bootable usb drive, installing ALL new drivers (provided by acer), flashed BIOS and manually offered every single driver my laptop uses but still no luck!

The error I get occurs when I have done this {
1. Inserted DVD/USB
2. Booted from the one inserted
3. Chosen language
4. Clicked install

The error message is this:
A required cd/dvd drive device driver is missing. 
If you have a floppy disk, CD, DVD or USB flash drive, please insert it now.
Very, very interesting! I booted from the DVD drive and I get this message, it must have been driven by magic when it first booted up. I get the same message even if I boot from the USB drive.

You might be interested in my current boot settings - Vista x32 Home premium, Vista x64 Ultimate (Unactivated, expired) and Ubuntu(on the buffalo external).

Do any one of you have a solution (trust me, I have searched the whole internet for a solution)

I cannot install windows 7 RC-finland_small.jpg

Moi Akke ja tervetuloa foorumille!

Sähän voisit kokeilla asentaa sen kovalevyltä. Jos ymmärsin oikein sulla on siinä koneessa jo käyttis asennettuna. Pura se ISO WinRAR:illa tai vastaavalla kovalevylle (ei tietenkään sihen partitioon mihin aiot sen asentaa!), ja käynnistä asennus manuaalisesti (setup.exe). Toimii!

Sorry, geeks, I couldn`t resist an opportunity to use my beloved Finnish, living here I can not use it so often.

I told him here above to try installing it from HD; first extract ISO to HD and start setup manually from there.

Ihanaa että on olemassa suomalaisia tässä foorumissa, maailma on pieni!

Ok siis jos ymmärsin oikein niin minun ei tarvitse bootata kovalevyltä? Voin vaan asentaa sen suoraan windowsin alla? kokeillaan!

Just told him that I'm greatful that there exist finlanders on this forum others than me!

And then I asked if I can install it directly under windows? Gonna give it shot!
