Luks/Encryption after install
 

Is it possible to encrypt my hard drive after a Centos load? Do I need to reinstall?

sam

Yes.
Certainly easiest.

Way too many variables:
- the entire disk ?.
- separate boot partition ?
- UEFI ?
- LVM ?
- CentOS version ?.
...

Most of us aren't mind readers.

Caveat: I know nothing about how to encrypt drives.

The last place I worked would set up and configure a new laptop (Windows 7) and then start the whole disk encryption process.
...but syg00’s questions are still valid...and I’d add
Hardware?
HDD or SDD?
