Install Macintosh OS 7.0 on Macintosh SE

Specs: Macintosh OS 7.0, Motorola 68000 @ 8 MHz
I want to re-install Macintosh OS 7.0 on my Macintosh SE. There is a lot of unneeded data on it which I would like to get rid of. I have downloaded the floppy disk images from Apple, which are in .image.sea.bin format. How do I copy these images to floppy disks?

The Macintosh SE does not have an Internet connection, therefore I need a Windows utility that is able to write (compressed) Macintosh floppy disk images to 3½" DS HD floppy disks.

Maybe RawWrite

I didn't know that apple allowed free copies of its software, but I am not that familiar with apple stuff. I guess if I was working in your situation I would ensure that its a legal copy and all.

These files are hosted on Apple's FTP site, so perfectly legal. They are self-extracting disk images which you extract on a Mac. (Catch 22.) They are intended for updating systems rather than bare-metal installs. So I think you need to find someone with a Mac running a pre-OSX OS.

I don't know of another way to etract these images, but perhaps someone else does.

Thanks ijack, I remember using rawwrite to copy a self extracting windows utility disk, so I figured it might copy the iso with no trouble.

Thanks for the answers, mikelinus and ijack. I will try RawWrite, and if that doesn't work there's no solution for me.

My Macintosh SE is currently already running OS 7.x (I can't remember which minor version at the moment).

I know my neighbours have a Mac, but it's a new one running OS X, which (of course) doesn't have a floppy drive.

EDIT: RawWrite successfully wrote the image to disk, but my Mac does not recognize it. Is there any other solution?

WinImage can copy MacIntosh 1.44 MB floppies, but it cannot view the files inside the image

Thanks for the information, mikelinus.

I followed the procedure and managed to successfully write six Macintosh OS 7.0.1 floppy disks (1,411 kB). However, these can't be read by my Macintosh SE, which has an 800 kB floppy drive.

Floppy disk images in 800 kB format were available on the Apple website, but WinImage cannot write them. It either gives an error saying that the image cannot be read or it just doesn't do anything at all (blank window). I have read elsewhere, that 800 kB Macintosh floppy disk images can't be written from within Windows at all.

So, I guess that means that there's no solution for me?

Mac OS 7 became opensource/ freeware back in the 90's and Apple even hosts the files for download on it's own site. According to this post on the Mac SE, you can put and format 1.44M floppies in an SE by converting them into 800k: The 1.44MB floppies you're using can be modified to be 800k by putting some tape over the hole adjacent the write protect hole. Windows should be able to see 800k floppies. From recollection, the issue isn;t the size of the floppy but the format needed so that they can be read by Windows let alone the Mac afterwards

Thanks for the information, richardtj. The problem is, however, that the image I'm writing to floppy disk using WinImage expects a 1.44 MB disk, not an 800 kB disk. I'm willing to try it, however. I'll let you know. Thanks again.

My Macintosh still does not recognize the disk with the piece of tape over the hole - it gives the same error as before.

The website says I will need an AE HD+ external floppy drive to be able to use HD floppy disks.
