Bios Mods -The Best BIOS Update and Modification Source

Now this sounds perhaps out to lunch but is there a mod that can convert a 2010 vintage BIOS to be UEFI capable?
BIOS and MBR only recognizes or allows 4 partitions whereas UEFI or should I say GUID/GPT allows many more and this problem is installing a dual boot Windows/Linux system on my Acer Aspire One AO533. Windows takes a partition and adds it's system partitions, combined with Linux Root, Swap, and /Home along with an OEM Windows recovery partition placed on the Hard Drive from Acer. Now the partition I reserved for Ubuntu is indicated as unallocated and I cannot create the necessary partitions required. The utilities won't let me saying 4 partitions already exist. If I set up the hard drive to GPT the BIOS won't boot to it just like creating a bootable USB in UEFI and it won't be detected by BIOS. What options or possibilities are out there other than placing this Netbook on my driveway and driving over it or totally ripping out Windoze and only installing Linux?

This is not possible, unless manufacturer puts out BIOS update in that manner.

However, your parturition issue is easy to solve, you do not need GPT for anything.

The limit of 4 is only 4 primary partitions, and you can setup windows in a manner where there is no hidden partition or system reserved etc
To do that, first make the disk raw, and then from windows installer go to repair/recovery options to get command prompt before you get to the install stuff. Then run diskpart and setup a single partition the entire length of the drive, you will shrink this later with windows or resize with other partition tool once you are done with the install.

Diskpart >> List Disk
Diskpart >> Select disk 0 << Assuming this is target disk #, if not select disk based on what you see above, or remove all other drives until done with this)
Diskpart >> Clean
Diskpart >> Create partition primary align=1024 (Or leave off align-1024 if not SSD or extended format drive)
Diskpart >> Format quick FS=NTFS
Diskpart >> Active
Diskpart >> Assign
Diskpart >> Exit

Reboot to windows installer, when you get to the disk selection screen select this partition and do nothing else, click next. Once done you will have windows installed without that system reserved partition, and then you can either shrink partition with windows tools, or use a proper partition program such as EaseUS or Paragon etc. and resize the drive to whatever size you want. Do not move the front of the partition, only resize from the end/right side (move sliders right to left to shrink from back towards front)

Then once done, apply, reboot and setup your other needed partitions, taking into account what you learned at link above for creating only two more primary partitions and a logical, or a few logical etc. If you were only one partition short before, due to the system partition from windows, you wont have that issue anymore so may not need to mess with logical partitions
