Install ESXi 5.x from a USB Flash Drive.
1. Download an older version of SYSLINUX because the newer version won’t work in this case. (http://www.kernel.org/pub/linux/utils/boot/syslinux/3.xx/syslinux-3.75.zip)
2. Extract the zip somewhere on your computer.
3. Download the current iso for ESXi 5.x install.
4. Extract the ESXi 5 installable ISO to a folder.
5. Format your flash drive with FAT32.
6. Open a command prompt (Open as admin if you are a ‘tard and haven’t shut off UAC)
7. Navigate to where you extracted the SYSLINUX zip file from step one.
8. Navigate to the win32 subfolder (Syslinux\syslinux-3.75\win32)
9. Execute this command syslinux –mfa F: (F: is the drive letter assigned to your flash drive, could be anything.)
10. Copy the contents of the folder for the ESXi 5 install you expanded from the iso.
11. Rename two files:
a. ISOLINUX.CFG gets renamed to SYSLINUX.CFG
b. ISOLINUX.BIN gets renamed to SYSLINUX.BIN
12. Boot from USB and install ESXi 5 much quicker. J
