No bootable device

I recently brought a Aspire e-15 E5-573G-53DS from a brand new store two weeks ago and I'm having this problem.
My computer wont boot from my hard-drive,
My HDD Model Name is WDC WD10JPVX-22JC3T0
This appears in Bios but it wont let me boot from it
My warranty will fix the problem but due to christmas holidays this process will take 4 weeks but I'm going away on a long holiday in 7 days and need it fixed urgently by then.
So is there a faster solution, like buying a new internal hard-drive, or if the HDD Model Name and Serial Number is appearing in Bios could it mean I have to buy a new windows and boot it from the disk drive? Please help.
