Windows 7: Please help me with a clean install of windows 7

This is how I use to install Windows 7, I had a cd-rom and I just put the the system recovery disc, waited for it to load, then clicked on the command prompt icon, command prompt opened, then i just looked for the partition and folder where my Windows 7 installation files are, once there in the folder, i typed setup.exe
The installation screen opened and follow all the steps, selected the partition c: where I wanted it to be installed, and it was fine


Now, I have no cd-rom and system reapir disc, so I opted to use grub4dos to boot "system repair disc" or a software kind of similar called "pcwindowsrecovery" from SD card(2Gb) or a USB drive(1 Gb), my goal was just to open the command prompt and look for my Windows 7 installation folder on a secondary partition, everything was normal but when I got to the drive selection to install Windows 7, and selected like always the C:, I got this error:


That's not my screenshot, but the error is the same, I have three partitions on my hard drive, with the CD-ROM booting system repair disc, i had no problems, but now with the SD or USB i have problems, I even format the partition but it wont work, do I need to fix anything using diskpart before looking for my Windows 7 on my hard disk and run the setup? Any help o method to fix the problem? why with the cd-rom method worked fine, but with the SD and USB, it does not?




I hava the SD card, is there any way I can use YUMMI or grub4dos, to install windows 7 but without having to put the all the installation files into the SD CARD, I can easily create a Windows 7 installation from SD, but it wont fit since the SD is 2Gb, how can boot grub4dos to install Windows 7 which i located in a secondary partition on my hard disk?

why don't you just clean up and start fresh the normal way. You seem to be drastically over complicating this. Have a look here to get your drive cleaned up, it needs to be wiped after all that partitioning madness.
SSD / HDD : Optimize for Windows Reinstallation

I dont understand, There is no complication, I always used the system repair disk just to use the command prompt and install windows 7 doing clean install I EVEN USE ACRONIS TO WIPE MY C: PARTITION

PROBABLE YOU MISUNDERSTOOD ME, that screenshot is not of my hardrive but the error is the same, I have three other partitions with data , and it is the C: where I always do a clean install of Windows 7, but in this case using the SDD or USB to boot system repair disc and use command prompt gives me the error which i did not have using the cd-rom, thanks for your help after all

Do you have a valid Windows 7 installation disc?

If you don't, you can download a legal ISO and activate a clean install with your existing Product Key.

I'm not sure you are going to get a "clean install" with a recovery disk or whatever it is that you are using.

The System Repair Disk only repairs unbootable Windows 7, not reinstalls.

To reinstall follow the same steps for retail as for Clean Reinstall - Factory OEM Windows 7.

Everything you need including the latest official ISO and tool to write it to flash stick or DVD is there.

I had a CD-ROM and the system repair disc, but did not have any discs to burn the windows 7 iso, so I just extracted all the windows 7 iso into a folder on one of my hard disk partitions, and I use the system repair disc only TO USE THE COMMAND PROMPT so I could search the folder and open the setup from my partition using the COMMAND PROMPT(which is included in the system repair disc... but since I no longer have CD-ROM, but I have a SDD(2Gb) and a flash drive(1Gb) in both I can boot the system repair disc or "pcwindowsrecovery" in order to open the COMMAND PROMPT and search for the Windows 7 folder in my hard disk to install, I do the same as I did when I use the CD-ROM to boot "system rapair disk" and the installation setup worled fine and would let me install windows 7 on my C: partition without any problems, but in this case when using SSD or flash drive, the setup wont let me install windows 7 on the C: partition,

I have windows 7 iso extracted on my partition, and is fine and it is preactivated and it is 3.5Gb, no problem at all in past when installing using "system repair disc" booted from the CD-ROM, but when booting "SRD" or anysoftware that would let me use COMMAND PROMPT from an USB or SDD I cant install a clean windows 7

No you dont get it my friend, I ONLY USE THE COMMAND PROMPT to open the setup that is located in one of my hard disk partitions, which worked fine i if booted "SyReDis" from the CD-ROM to do a clean install, the windows 7 setup opened by using command prompt to look for it on my hard disk partition, and the setup would LET ME INSTALL WINDOWS 7 on my C: partition without any problems at all,

now that i have NO CD-ROM, but still i have my extracted windows 7 iso in my partition, I boot "SYReDis" from my USB or SDD, then I open COMMAND PROMPT, I look for the setup in my partition, and the setup window opens fine, but this time the setup wont let me install Windows 7 on my C: partition, if I boot "SyReDis" from an USB or SDD

Is there some reason you cannot boot a DVD or write the Windows 7 installation ISO to flash stick to boot it to install? Everything you need is here: Clean Reinstall - Factory OEM Windows 7 and is the same for retail.

Yes, the reasons are I no longer have a CD-ROM UNIT, MY SSD IS 2 GB, AND MY FLASH DRIVE IS 1GB and the original oem windows 7 is 3.60GB
These is how I use to isntall windows 7 iso extracted on a partition,
-I had a CD-ROM unit, and the System repair disk
-I put the system reapir disk on the CD-ROM UNIT, and waited until the menu, I clicked the command prompot and use the commands to find my Windows 7 iso extracted,
-then typed setup in the command prompt, and the setup installation would open,
-I followed all the instructions and selected as always the C: partition(formatted or with data to install windows 7, and it installed fine, no problems at all.

Now I do the same, but instead of using the CD-ROM TO BOOT THE SYSTEM REPAIR DISC, AND USE COMMAND PROMPOT, I USE AN SSD OR THE USB, WHEN I TYPED SETUP IN COMMAND PROMPT, and the setup installation appears, I follow all the instruction, but when I get to the partition selection to install windows 7, which is always C:, I get an error, which never appeared when booting system repair disc from the CD-ROM UNIT

You're trying to trigger Setup in the extracted Windows 7 files stored on the partition shown in the screenshot?

Since you have the Drive Options opened it appears you might have just formatted the partition which does not show any content in the listings.

If you were able to extract the installer files to a folder on the HD, could you not have run Setup from the Windows 7 desktop to overwrite C, as can be done? The installer files would wind up in a windows.old folder along with everything else from the old install. You could also extract them to another partition to run.

BTW 4gb flash sticks are $5 with free shipping on buy.com.
