Getting a file to Samsung Galaxy Tab from my Laptop without Android?
As I said in my comment, you should be able to flash using Odin. I'm not sure it works through a VM though, so perhaps you might have better luck with Heimdall.

Basically, you need to get the appropriate firmware for your device from here (signup required). Then, shut down your device and boot it while holding volume down + power. Once the tablet enters download mode, connect it to a PC. 

If using Odin, the file you downloaded goes into the PDA box. I'm not too sure about Heimdall, but it looks like the downloaded file goes into the "Heimdall firmware package" box. Then click "Start" in Odin and wait for your device to reboot. 

At this point, the tablet should boot into Android.
