win8dev installing ... cd/dvd driver missing error

Question

i have tried to install the 64bit Win8 dev prev on all 3 of my machines and get the same "required cd/dvd device driver missing" error on all 3 computers ... thought maybe my dvd burn was bad so i did a second burn with a different burner software.  all 3 machines same error.

never had any install problems with windows 7 betas ...

saw 2 other people having this problem on here but no one has any kind of working solution posted ... 

not a good first impression for win 8.

Answer 1

Try re-downloading the ISO.  It can become corrupted during the download process.  If you check the MD5 hashes, it will be different from what is shown on the website.

Answer 2

i redownloaded the 64bit iso and tried again .... same error ... downloded the 32bit version to try on my netbook .. same error ... i had a new bump this time ... when i used the built in windows iso burner i got a invalid iso error ... but it burned fine using my roxio burn programs 

don't know why i may be getting bad iso's but everyone else is not.

 

Answer 3

i think i figured out my issue but have no solution ... i am not getting the whole ISO when i download i think ... when i start the download it says it's supposed to be 3.6gb ... the downloaded ISO in the end was only 2.2gb.

Rich Prescott was right.

Answer 4

how do you check the md5 hashes?

Answer 5

Download FCIV from http://support.microsoft.com/kb/841290.

The sha1 hashes are listed for each iso at: http://msdn.microsoft.com/en-us/windows/apps/br229516

Then run the following to check the sha1 hash:

fciv.exe -sha1 <path of iso>

 

For md5:
fciv.exe <path of iso>

Answer 6

Or if the command-line scares you there's also Hashtab:  http://implbits.com/HashTab.aspx

 

This adds a file hashes tab to the properties view you get when you right click on a file.

DarthG,

Developer's Preview means BUGGY. Thats why we have beta testing to get the BUGS out. Its good to go through this. It isn't like Microsoft is going to just send'er out of the ole garage for people to load a program that won't load.

I am having same problem. Can't install this thing on any PC I got and have attempted downloads three times. Download finally full versions twice. Both will not load on anything in my house and I have 9 computers and home office.

I was wondering if they had a similer program to Win7 Beta where you could get the disk already burned from Microsoft. I have a "BucketNet" DSL connection. My download speed starts with a hefty 300 to 400KB then when the Bucket is empty I get to snooze at snail speed {30kb} downloading for 2 days. My entire family and business gets put on hold while downloading because the bandwidth gets so weak.

Answer 8

Are these newer machines? Do they have Advanced Technology drives? I've been digging into the same error on this thread http://social.msdn.microsoft.com/Forums/en-US/windowsdeveloperpreviewgeneral/thread/d9cf76f4-ceae-4e4d-b87e-00a52bac861e .

To see if you have New Technology drives try using (as administrator)

c:>fsutil fsinfo ntfsinfo c:

and see if it returns a physical sector of 4096. If it does then you probably have New Technology drives and you are running into the same issue I am.

Dan1580,

Okay, according to your test my PCs are fine my net is not. It tends to run "at off again on again" modes and trying to set it to always on is not possible. Our provider does not like those nifty long term downloads and drops us to "Net only at Night" as a nifty punishment for a week after a long download.

I found out the downloads were bad.
