Ok…this has been said a few times in this forum, but let me write-up a detail of what has worked for me, and I believe a lot of other people in this thread as well…
First, my setup: I have Vista 32-bit Ultimate installed on C drive…which I use all the time. On my 1TB D drive, I had a Windows 7 Ultimate 32-bit RTC installed…I used it sporadically and the license was about to expire. I bought a student license for 64-bit Windows 7 Professional. Yes, this is an upgrade software, but you can do a clean install over any previous version of Vista or Windows 7 as long as you have Vista or Windows 7 installed on the drive you’re trying to use the upgrade software for.
Let me repeat. If you bought a new blank hard drive, or formatted one of your hard drives, and are trying to install this UPGRADE version of Windows 7, regardless of whether you use the upgrade or clean install method, it WILL NOT WORK. You may have no issue installing Windows 7 on the drive, but you’ll have a problem with the activation key.
So, you MUST have a working or non-working copy of Vista (and I assume XP works too) on this hard drive…again, DO NOT format the drive…let Windows 7 take care of that for you during the installation.
When you get the e-mail from Digital River, click on the link and download the files… you will end up with 3 files:
setup1.box
setup2.box
Windows 7-P-Retail-en-us-x86.exe (My folder was 3,319,083,754 bytes and 875 files in 199 folders)
Click on the last file (the .exe). it will create a folder called ‘expandedSetup’ (with no quotes of course).
At this juncture you may get an error saying: ‘We are unable to create or save new files in the folder in which this application was downloaded. Please check the folder properties to make sure that you have security permission on the folder to write files and that the folder is not read-only’…
IGNORE THIS ERROR… your folder called ‘expandedSetup’ has most likely been created successfully. Now you need to BURN this folder to a bootbale DVD.
1-Copy the entire folder of ‘expandedSetup’ to your C:\ drive.
2-Download oscdimg.zip (posted by OP)
https://www.sevenforums.com/attachmen...-l-oscdimg.zip
3-When you unzip the oscdimg.zip file, it will create a .exe file of the same name called ‘oscdimg.exe’ copy this file to your C:\ drive.
So, Copy two files/folders into your C:\ drive
a.Oscdimg.exe
b.The entire folder of ‘expandedSetup’
4-Go to Start then Run then type ‘cmd’…this will give you the good old fashioned DOS prompt
5-Type this after the C:\ prompt:
oscdimg.exe -u2 -bC:\expandedSetup\boot\etfsboot.com -h C:\expandedSetup C:\7.iso
type the above exactly as is…for example, there is a space before -u2 -bC and -h
(there is a picture of this posted by Sharivari a few pages before this post, I think page 8)
Once the process is complete, you should see something like: Final image is xxxxxxxx bytes, Done. This means the image for your Windows 7 has been completed and now you need to burn that image on a DVD. The image file is called 7.iso and should be on your C:\ drive.
6-I used Nero Express. Fire it up, and this may be different for various devices, but it didn’t allow me to burn at high speed…I had to try it a couple of times, and finally I set the burn speed at a very low rate of 4x and the image was burnt on the DVD
7-Restart your computer and the installation should start from the DVD. If it doesn’t, you may have to press something like an F8 to get a menu to start from the CD/DVD drive, but this is highly dependent on the PC/BIOS you have.
8-When installation begins, make sure you pick the second option on the list, which is a ‘clean install’. After 30 minutes you should be up and running
