My linux partition boots 99% of the time first time.
For my windows partition, that score is closer to 5%.
Many times it hangs on the black screen with the wobbly windows logo. Only holding in the power button gets it to stop. Windows repair often does nothing. Leaving my windows partition unused for a week seems to fix it sometimes.
Sometimes it just cuts out. Goes from fully working to off in an instant, like I'd pulled out the power cable.
Windows and Linux are on the same hard disk. They are using the same hardware. Windows doesn't work right. Linux does.
Oh, and I have 0 funds to get it fixed.
