cannot create system repair disc error 80070057

Hi

I'm using Windows 7 ultimate RTM and cannot create a repair disc image anymore. i get the error code 0x80070057 incorrect parameter with a dvd inserted. I'm really not sure what's causing this...

Thanks in advance for any replies

Curious error - do you only get it when trying to create a recovery disc?

Is windows all up to date?

Dvd is a waste - it fits easily on a cd-r.

yeah. all the latest updates are on windows from the windows 7 page (of course not all the optional updates but those are irrelevant anyways). Well I can try a cd-rw next time around if i can get this to work somehow.

I'm wondering if repair installation might be a good idea to fix this if there aren't any other options

Thanks for all the replies.

I did a repair installation and it does create a repair disc but requires me to insert the installation disc first. Only after that can I insert a blank disc to create an image.

Is that unusual?

Strange - have a look on the root of the drive for a hidden folder called Recovery. It claims to be empty.

Copy and paste it to your downloads folder .It should containn boot.sdi and winre.wim.

apparently I don't seem to have that. I only have a main partition (C:) with 9mb unallocated and then it just shows the optical drive in the disk management.

Go to folder Options - show Hidden Files and protected o/s files - find the Recovery folder - follow steps in my previous post.

I did copy the recovery folder to the downloads folder and it does contain the files you mentioned but I'm still getting insert windows 7 installation disk before I can create a system repair disk.

Apparently there's two copies of winre.wim in the subdirectories of the recovery folder if that's relevant. One in the Temporary subfolder and one in a subfolder that's named with a lot of numbers and dashes that also contains boot.sdi

Thanks for the advice though
