How do i put a older os in my pc i cant delete the current one can anyone tell me how to delete my c:?
search for Gparted after doing a backup of anything important and then after erasing everything with gparted insert the old OS cd and boot your pc with it
Reply:Boot off of the old OSes cd or floppy. As you progress through the installation; it will ask you to partition your drive. When you do that, select the "C" partiton (probaly the only there) and delete it. Then it is gone and you could continue the installation.





You could all use the tool gparted to delete the partition:

Reply:Just insert the OS disk and in the setup options install the os over the old os
Reply:To reinstall Windows, you will need a Startup Diskette and a Windows Installation CD.





Download it from here:

1. Once you have your Startup Diskette, insert it into the floppy drive and restart your computer.





2. Select option #1 - Start the computer with CD-ROM support.





3. After a minute or so, you will see "A:%26gt;_".





4. Type "fdisk" and press Enter.





5. If asked to enable large disk support, select Y for Yes. (Note: Some versions of Windows 95 may not be compatible with large disk support. Select N here if it does not support the FAT32 file system.)





6. Select Option #1 - Create DOS partition or Logical DOS Drive.





7. Select Option #1 - Create Primary DOS Partition.





8. The drive integrity will be verified.





9. Unless you are planning to make multiple partitions, select Y when asked if you want to use the maximum available size for the partition and to make the partition active.





10. The drive integrity will be verified again.





11. When completed press the Esc key to exit fdisk.





12. Without removing the floppy disk, press the reset button on the computer or press the keys Ctrl then Alt then Delete and release them together. This will restart the computer.





13. Again, select the option to Start the computer with CD-ROM support.





14. When you see A:%26gt;, directly above it is a message about your CD-ROM drive. It will tell you the letter assigned to your CD-ROM drive, take note of it. The screen will look something like this:











15. At the A:%26gt;, type "format C:" and press Enter.





16. Press the Y key then the enter key when asked if you want to proceed with the format.





17. The format will probably take some time, so be patient.





18. You will be asked to choose a Volume Label, which is a name for your hard drive. It has no effect on the operation of your computer, you may choose any name you like.








Hope that helps,
