IDE cable or Hard drive switch .. Drive 1 and drive 2

  I don't have a lot of luck with a dual boot system. I do a lot of
downloading and getting viruses and a lot of reinstalls and other
playing around. Dual booting just don't work for me.

I want 2 hard drives. Each has its own OS. I want to flick a switch to
switch from one drive to the other. Currently I pull the drive bay out
and remove the IDE cable from one drive and plug it in to the other.
Its just a matter of time till I screw up the pins or something. This
is why I want a switch. What are my options...affordable ones?

SATA trays also sold.  Check newegg for them

I use the IDE trays with zero problems

  How do you control which drive boots? I have a drive bay with a key switch,
just used for testing drives.

 You dont. This is intended to solve this problem he stated he wated to
avoid.

In the past I've used similar removable trays for this: simply buy
two trays but only put one drawer in the machine - obviously it
will boot from whichever disk is in the machine at the time.  Or
have I misunderstood something?
