Hello everybody.
While I was messing around with my laptop, I decided to add on a fourth operating system, Arch Linux. I suppose I was pushing my luck a bit . Anyways, during the installation, I accidentally deleted the EFI system partition from my laptop, which contained the Windows Boot Manager and necessary files to boot. Great. I only made things worse by trying to troubleshoot, and broke grub as well.
I have a Windows 8 repair disk I made using the Windows 8 built in utility, but it does not boot: the computer turns on, and just hangs at the Toshiba splash screen.
I also can obviously not access the Toshiba recovery partitions, as they are booted into just like Windows itself.
I found a bootx64.efi file on one of my system's recovery partitions (Toshiba seems to have some really complex system going on) and placed it in \EFI\boot\bootx64.efi. According to this site, FGA: The EFI boot process., I need to place the bkpbootmgfw.efi (on my system, that was what it was called, but I suspect boot-repair (ubuntu tool) messed something up when I was first setting up grub and the ESP and the bkp stands for backup) back onto the EFI System Partition.
The BIOS and underlying GPT all seem to be working, as I am typing this from a Linux Mint live USB. If anyone who has a UEFI based system (probably any computer that came preinstalled with Windows 8 has such a system) could acces their EFI partition and upload it for me, I suspect my computer will boot again and from there I can get on to fixing grub. Even better would be someone with a Toshiba computer, as this post (grub2 - Unable to boot Windows 8 after Ubuntu installation - Ask Ubuntu) makes me suspect all Toshiba systems are the same in this regard. Someone with a Toshiba could then provide me with the system specific .efi files which are used to boot into the recovery partition.
If not, someone with experience with WindowsRE could perhaps tell me where to look for in the various Windows Imaging Format .wim and .swm files I have laying around my recovery partition(s) in order to extract the necessary EFI files. Most pertinent information can be found in this thread: EFI System Partition deleted - can only boot from Live CD / Newbie Corner / Arch Linux Forums . I would also much appreciate if someone was willing to supply a Windows Repair iso that works for them. I will edit this post shortly for the exact error code Windows Boot Manager gives me (i can access it from that lone bootx64.efi file I placed on the ESP).
Thank you very much for your time and support.

I put in some files from recovery partition, and now get this:
