hello

new to community..i've been using linux for years now. last install was debian wheezy (testing). hardware is lenovo edge e325 (amd brazos e-450, 1.6 ghz, 4gb ddr3 ram, 300 gb sata, radeon 6320 fusion vga). debian maintainers f***ed up properly with last update (broke my system completely). wanted to install debian stable but its really old snapshot. soooo, i found pc-bsd. i'm under impression bsd community is growing and decided to give it a try with pc-bsd. installed official stable 9 release x64. i have no need for raid, so i chose UFS, entire disk option, and default layout of partitions in advanced tab. installation went well. ejected dvd and clicked finish. after setup screen the only thing it says is : Operating system not found.
no prompt, no options.
after some research, it seems it has some connection with partitions. is it possible that pc-bsd instalation saw old linux partitions and screwed up them so i cant see them, but they are active and messing my boot process.
funny, many people have that problem after ANY os new-install. win users often solve their problem with recovery console and fixmbr (fixing mbr command). is that my problem? where is pc-bsd's recovery console or something similiar?
(and yes, i tried combinations with uefi or legacy option in bios-didn't work)
any help is really appreciated
