Actually No. The Hardware will still be of the original size, and the BIOS doesn't really look into Partitions.
There used to be and old piece of software, that would make the Bios recognize the full size of it. I used it a long time ago on a Compaq Desktop where i replaced its factory 2Gb drive with a new 20Gb drive, and had to use the software for its proper functioning. However, the name escapes me at the moment.
But depending on the OS, it might recognize the full drive without it and even though the BIOS doesn't.
WhatOS were you planning on installing on it???

Unknown has caused an Unknown Error on Unknown and must be shutdown to prevent damage to Unknown.
