Pay close attention to the part about installing GRUB (A Linux bootloader program) in your Windows MBR. Ubuntu will also find the shared FAT32 drive and your Windows NTFS drive (if you choose to dual-boot,) so you can usually ignore the part about MOUNTing drives after install.
That's nice that your company allows that. Every salaried job I've held, it was all about how much they could pile on you.The last salaried position I held, it was the norm to be under a "mandatory overtime" policy - 50 hours per week min, no extra pay. But when the rare slow period came around, there was no leaving - I had a higher-up tell me that there was always cleaning I could do.
