an easy- to- use PCB software

KiCad [...] and gEDA [...] are each free, open source suites

TinyCAD and FreePCB are also FOSS and work quasi-well together.
(Windoze-only, but both will run fine under WINE.)

[...]gEDA. As far as I know,
there is not an official MS Windows distribution available.

Previously, they had produced Windoze-compatible binaries
but they stopped when the mailing list got cluttered with inane
questions
from people who could barely use Windoze--much less use an ECAD.

Dan McMahill maintains the build script for getting gEDA going under
Windoze.
If you can get thru that successfully,
it demonstrates that you might be qualified to use the package.

Some boot-to-a-desktop Linux disks contain both gEDA and KiCAD.
Ubuntu Electronics Remix and Fedora Electronic Lab Spin
are probably the most up to date.
You can run those without installing anything.
Ubuntu and Fedora can write to FAT32 and NTFS partitions.

....and this question doesn't qualify as "repair".
Questions about ECADs belong in sci.electronics.cad
just as beginners' questions belong in sci.electronics.basics.
