I have a Dell Vostro 430 that i would like to do a factory reinstall of the OS i don't have the original disk and i can't boot into the machine to get the recovery program open anything i could do?
Unless you find a way to reinstall from your recovery partition, you may have to forego the idea of doing a factory reinstall and just do a clean install instead. You can do a clean install as follows:
1. Follow the instructions in this article to download a Windows 7 ISO from Microsoft Tech Bench. There is no telling when this workaround may stop working, so you should act quickly.
2. Once you have the ISO, go to MSDN Subscriber Downloads and use the box that says "Enter a Product Name" to search for the same ISO.
3. Once you find the matching listing, click on the link that say "Details" to expand the listing. (Note, you won't be able to download anything at MSDN without a subscription but we just want the SHA1 hash).
4. Locate the SHA1 hash and use something like Hasher Lite to compare it with a SHA1 hash of the ISO to make sure they match. This will ensure that the ISO wasn't corrupted in the course of downloading.
5. Next, follow this article to make a bootable Windows 7 USB flash drive with Rufus.
6. Download MiniTool Partition Wizard Bootable CD from Minitool (the penultimate listing on the page) and burn it to a CD or create a bootable USB drive.
7. Boot from Minitool PW delete all existing partitions on your hard drive. You must click the Apply button to apply the changes.
8. Remove the Minitool media and insert the Windows flash drive and reboot your computer.
9. Follow the prompts to install Windows on the new hard drive. You may need go into the BIOS to change the boot order if the computer doesn't boot from the USB drive.
10. Download all drivers from your computer manufacturer and install them.
