Does it happen to have room for two drives? ...if so, you can still do this, just pop one in, load OS, remove, pop the other load OS... place both in, choose OS by changing boot order. One of my laptops has two drives in it but it's not as common on lower end models (or smaller/sleeker models).
Oh well, sometimes you don't think about things like that until you've already purchased the product. Now you know for next time, make sure the hardware is reasonably accessible. I just bought a new desktop and it has easily removable SATA drive bays, so I load different operating systems on different bays. I can easily swap drives when I want and they also have a key lock so I can secure them if need be.
I wanted to use my Laptop sim card slot for connect internet
Model: Lenovo edge E430
I've never used any Lenovo laptops, but back at my last IT job I had to get this working with Dell Latitude E6330. To get the SIM card to work I had to reinstall the Wireless LAN Controller software/driver which detected the SIM in the slot and initialised it during installation. All worked fine after that.
It maybe some what different for the Lenovo, but I reckon it will be similar.
