Okay- consider me pretty much compouter illiterate and just plain ignorant- so here is what I want/need to do-- when Lion first came out, I strated the downlod from the Apps store and poked around on the Intetnet- waiting-- then panicked when I saw that my software (with over 20 years of records drawings etc.) would immeditely become inaccessible if it installed. I put in a thumb drive and moved everything to it. Now (I never knew ML existted because if I go to it- I still will lose all my fiues etc--but now I have a non-apple workaround planned, but I have no idea what I am doing, just following directions!). I am going to try to put ML on n External Hard Drive and get my iMac to boot from it when i don;t need Snow Leopard-- So here is my question-
1)first-can I take the never used Lion and wipe it and use the same thumb drive (which has been patioently sitting in the zippered case for over a year now- untouched)? It is an 8 GB thumb- so even if they could be there together, I suspext the size us too small? Should I just go ahead and have two thumb drives one with ML and one with Lion-- then go ahead and install on the ext Hard drive (that I have not yet purchased and Apple would not suggest any brands)?
2) I was told to, just in case I really foul things up (remember my inept status) back up the current (SL) hard drive-- I am running Time Machine---is that sufficient and if it is--AND I need it (becuase I goofed) how tdo I restore the current hard drive----or to be safe do I just go ahead and buy yet another Ext HD D and copy the whole contents onto it for safekeeping until I know...??
I am hoping this will allow me to both have ML available and access SL with those files as I need them (in case anyone is curious- they are ll in FreeHand and that is now totally dead- I kept hoping someone would do an 11th hour recovery-but not going to happen-so I need to try to move on).
Obviously I cannot take the "risk" of ML actually installing on my iMac--so that is what I want to avoid-- just checking!!
thanks--
