Windows 7 guest installation problems

[peperami]

Hi

I am running Virtualbox 3.2.10 r66523 on Debian. My machine is a 64 bit amd.

I had a problem with a windows 7 guest that I was using and I decided I would reinstall. So I wiped the hard drive and reintalled using a mounted iso of 64 bit win 7. It failed with a problem during expanding Windows files. The message is Windows cannot install required files. The file may be corrupt or missing make sure all files required for installation are available and restart the installation. Error code 0x80070570. So I completed deleted the machine, all settings and the disk and tried again. Same problem. Tried a different win7 iso and same problem. Downloaded the ISO again and same problem. I would be supprised if the ISO's are faulty, as I am an msdn subscriber and they are downloaded from the member site.

Any ideas of how to progress this please ?

Thanks

I've seen faulty ISOs from MSDN on numerous occasions, so you have to make sure the checksums match with those noted on the download page.

I have downloaded multiple times on different machines, and the point of failure seems to move.

How can I check the sum on msdn cd's as the SHA1 that msdn reports is nothing like correct for any of the iso images I have downloaded. Including ones that I know work. I am using the command sha1sum to check them.

I have looked in the bios on my machine and dont see any mention of hardware virtulisation, but until my vm crashed this morning I was happily running 64 bit windows 7.

On Linux, the package and command 'cfv' will allow you to verify the checksums. E.g the following will check the CRC hash:

Code: Select all

cfv -C -t crc -f - <file you want to verify>

The output will be stdout, you terminal. If the hash is different, then you have a faulty download. But check what you are downloading with what you get. I've had most downloads come in ISO format, but I got offered .exe files instead, which were actually iso's when I verified it with the 'file' command.

Also, if you do NOT have VT-x or similar options in your system BIOS, you will not be able to run 64 bit guests. See the VirtualBox FAQ for some pointers in how to detect hardware virtualisation capabilities.

My host OS is Ubuntu 10.10. I'm installing Windows 7 on VirtualBox 3.2.12.

My progress was stopped by the message, "not enough memory for temporary files". I may not have the exact wording right as it's been a couple of days and have been too busy to get back to it. I'm hoping someone recognises the problem and can be of assistance.

Thanks.

I do have VT-x or similar based on the contents of the log file and the V appearing in the icon bar at the bottom of my vm.

However everytime I power on and off the machine during the install it gets a different % through extracting files before failing.
