I'm trying to get a hard drive working that has/had data on it. Tried OBCD's PartedMagic and 'Disk (External), writing 'dd' over all after I deleted the partition. Tried my 8.1 install disc but it gives Recovery error 'your pc needs to be repaired'.

Tried PM's secure erase 'Internal" w/writes zeros over all but get the error 'A password is to be used in conjunction w/this command' enter or use NULL, but when I try 'NULL' I receive 'In event of an unexpected issue ...' could brick the drive.


I'm afraid other methods may also brick the drive. Should I try FDISK or some other method from UBCD? If I can solve this I'm sure my install will work. Alternatively, might there be something in the Bios that's causing problems, w/I can alter using UBCD?

Thanks in advance for any assistance,

You don't need to zero the disk if you only want to install a new OS. What is the make and model of the computer? Did Windows 8.1 come pre-installed on the computer?


If yes then do a clean install per the following post. It a guide for Windows 10 but the steps are the same for Windows 8.1. Because the computer was pre-installed with Windows 8.1 the key is embedded in firmware if the computer was an OEM like HP or Dell. It's important you also initialize the disk as GPT. 




You can get the latest updated iso if 8.1 using the Media Creation Tool.
