Help re rubber flooring removal!

[yeknomyeknom]

Our rubber floor was bubbling in spots. As a surprise for my partner, due home in 2 days, I decided to pull it all up and lay some vinyl. A little Xmas refresh. I?ve pulled a third of it up. The rest will not budge. As you would imagine, someone used adhesive to stick it to the subfloor (thin osb). Any quick tips on how I might get the rest up? I?ve tried cutting it into strips, shimmying in under it with a palette knife etc. I will be in for it if it?s not done soon.
