Lost or forgotten Windows password
Last time when I was installing Ubuntu for my secondary OS on my desktop, the moment it success I forget the password…so I have to re-install the system again and reset the password. And this attempt works. Since reinstalling takes effect when you forget password in Linux, will it still work for Windows 7? I asked to myself and I want to test it on my Samsung laptop I bought years ago and the laptop I lost password too.
Before downloading Windows 7 ISO file I decide to find if there're more efficient solutions than my plan. I found some solutions but they turned out to be useless to me, some of them requires pre-setting and needs a boot CD to prevent you forgetting the password, but I already forgot it and I cannot boot into it to make a bootable media. Eventually, I found my plan is better than theirs.
Do I have to make a backup on the old laptop, let me think, it is a college period laptop, files are mostly courses related, no more importance; videos are watched, no need to backup; songs not much, games old fashioned; browse and purchase history shall be removed, saved password shall be wiped too. So compared to backup, erase is a must step to do before reinstalling. Besides, I can't even get into File Explorer, how can I make a backup? Just follow the steps below will do:
Step 1: Get ready
We have to get the following things ready before we get to steps of erasing disks and reinstalling Windows 7:
- 1. 2 blank disc: CD/DVD.
- 2. Data sanitation software.
One blank CD is for data erasing software and the other for the burning Windows 7 ISO file. You can also try burning ISO files to USB if the CD reader is broken or cannot read CD consistently, and you'd better prepare another proram to burn ISO file to USB, Rufus may be your choice.
Step 2: Erase the entire disk
Entire mean everything on the disk, you can follow the tutorial of erasing everything or you can just click on the Bootable media tab and create a boot CD of this Eraser. When you boot from the CD you can do as follow to wipe out the disk:
- 1. Click Erase disks and choose Disk 0, or the disk you installed Windows on.
- 2. Select the erasing method, simple, advanced, complex or very complex.
- 3. Click Erase now and confirm it in the dialog follow-up.
Erase will take up some time, depends on the capacity of the hard drive, the larger the longer, the more passes the longer. If the old hard drive has bad sectors, the time will be longer. After finished wiping, you can disconnect the boot media and insert Windows setting up disc instead.
Step 3: Reinstall Windows 7
Now install Windows 7 when successfully boot from the media, we have a detailed step guide in this page: How to format a computer, you can click on to read more or just simple follow the Windows 7 install wizard. Once you're in the account and password section, bear in mind to remember your settings and don't forget the password again, or we have to repeat these steps again.
