Hi all,

I have searched high and low for this answer with little luck on how to fix. I have built a new system (first ever) machine posts no problem (i think) I can get into BIOS and it sees both HD and DVD drive. I have boot priority set to DVD. When I put the Win7 disk in I get this error "CDBOOT: Couldn't find BOOTMGR"

I have booted the computer with the disc that came with the Mobo and it sees it. I have put the Win7 disc in another computer and know it works.

Any help would be GREATLY appreciated!!

Hi.

You probably burnt the DVD wrong and made a data disk.

You need to burn it as .iso instead.

Even though you were able to boot another machine with your current disc is no guarantee that it will work on yours.. You have built yourself a very high end machine and they tend to be very finicky... I would re-burn the ISO file (as an image file ) at the slowest possible speed. I would also remove all but one stick of RAM before attempting to install... Let us know how it comes out..

lol Tews and I must not be doing so well with reading lately...heh Tews?

I missed this part - "I have put the Win7 disc in another computer and know it works."
and Tews missed this - "it's a brand new out of the box disc (Win7 Pro)"

So LucRad, maybe you'll have better luck if you boot to a USB key instead. You can make one with the DVD you have on the other pc. To boot to USB, sometimes you have to set it to boot to HDD and then pick the proper USB key. And also sometimes, you can have boot choice instead, simply by hitting f8 at startup.

No matter what you do though, if there is a setting in the bios for Plug and Play OS - set it to yes (it's on all Asus boards so look for it - disabled as default.) And you might have luck booting to DVD if you change the AHCI setting.

Hi luc,

As has already been mentioned, the first thing to try is changing the disk controller in BIOS from AHCI to ATA - see if that helps.

See if there any driver updates for your mobo and dvd drive firmware from the mfr. websites.

Otherwise a bootable usb stick may be the answer - try the free WinToFlash.

WinToFlash - Install Windows from usb - Home page

Also, if you can boot a Vista dvd - boot to the cmd prompt on that - take the Vista dvd out. Put 7 dvd in and run the setup.exe that is inside the 7 dvd sources folder.

Hope it helps.

OK so far no luck..have ruled out bad DVD player as it ran other discs.

Have changed my "Storage Configuration" to IDE and AHCI. There is a third option RAID which I have not tried.
Have chnaged my cJ-Micron eSATA/PATA Controller Mode from IDE to ACHI several times
Have changed SATA cable
Removed all but one ram chip
removed sound card
unplugged and reseated sata, power cables (even tried a few different ports)

still stumped despite my best research

There is nothing wrong with your hardware. It is a conflict between the boot code on the Win7 disk and your hardware. For some reason this Win7 bootcode does not like some motherboards. Go to this site UNAWAVE - Code 5 Error whilst booting Windows 7 DVD and DO EXACTLY what he has laid out and you will load Win7. You will need a Vista disc, but not the whole install disc. Go here for that: How to Make a Windows Vista Repair Disk If You Don’t Have One :: the How-To Geek Take your time setting up the ISO disk and it will work. If I can do it (which is saying a lot) you can too! BTW, my motherboard was not one that was listed in the Unawave fix, so the problem affects others as well.

Burn the iso with this - the only thing to do is browse to the iso, and select 4x as the speed:

View attachment isoburner.zip

Put a cdr in - don't format it - click Burn ISO!

I just used the latest version of Imgburn and was able to set it up by following his screenshots. Just take your time. It probably took me 45 minutes, because I checked and rechecked and checked the recheck, before I was able to burn the final ISO.

Much easier to use the isoburner posted above. That's all it does.

Pardon my ignorance, but if he has a brand new out-of-the-box version of Win7, how is just burning a new ISO copy of that going to help? What worked for me was burning a new ISO with a reworked boot code from Vista. I had similar problems as him. My computer would boot to installation if I put in the WinXP install disc, but it wouldn't if I put in the Win7 disk.

Is that what he's doing?

Wasn't clear to me - thought he was just going to burn the Vista recovery cd and :
boot to the cmd prompt on that - take the Vista dvd out. Put 7 dvd in and run the setup.exe that is inside the 7 dvd sources folder.

Either way - the principle is the same.

Hey, I'm a complete newby to this. Never thought about just booting with the Vista disk then switching to Win7. If that works, great! Whole lot easier than what I did, even though it produced a working install.

Actually, it makes sense to create a dvd that works - saves messing with 2 when you want to install.

That's if the OP can get it to work.

Clarity...

- New system...no OS
- Other disks work in the new system (MOBO setup disk, Win xp)
- Win7 disk works in other computers, but not on new system.

as of last night I installed WinXP(which it took ...no problem) and then tried to install Win7 this morning and got a 32 bit error of some kind saying it wasn't compatible with 32bit os or something of that nature...will recheck it tonight.

Tonight I'm going to try the dvd drive out of my old system.

So far all I can possibly bring it down to is there must be some kind of compatibility issue with the MOBO or DVD being able to read the Win7 coding....dunno if that makes sense but I'm no computer geek.

Thanks for all the help so far....stay tuned...LOL and keep the ideas coming!

So, did you complete the Unawave instructions on making a new disk with the Vista boot code? You already have the solution to your problem. You just need to implement it.

PROBLEM SOLVED

Incompatible DVD drive...would not read 64 bit software.

I put in my old DVD drive and off it went.

Thanks everyone for all your efforts!
