Sorry it took so long to get back, things have been really hectic lately. This disc was used to install both before & after trying on hers. On 5 other machines the disc gave me no problems at all. I finally used LLVMech_63's suggestion of unetbootin on usb stick - everything went great & she LOVES PCLinux, vows to never use Windows again. Even better, her son-in-law (who bought her the laptop) was having issues with Win7 (said he hates it, even though he is a 'Windows guru'. He tried the LiveCD, but had the same problem I had (his is also G72). I sent him the LiveUSB we used on hers, now he's PCLOS too. He said 'this OS is everything Windows 7 was supposed to be. I love it.' Kudos to Texstar and the dev team - keep up the good work!
