Welcome!
Is the disk you have an authentic Apple Jaguar installer or a disk someone burned? Historically, PowerPC Macs had trouble installing an OS from any burned disk.
Per this Apple article: How to download and install macOS - Apple Support
the oldest macOS version for which they still offer a legitimate download is 10.7 "Lion," which cannot run on any PowerPC Mac. Downloadable OS installers from other than Apple have zero provenance for determining their fitness for purpose.
My esteemed colleague Nick brings up a good point when he mentions "machine-specific" installers. The system install/restore disks that Apple used to ship with their computers often had special files needed only for the specific model, even sub-model, with which the disks were included. They often failed to work on a different model.
Legit full-retail install disks are bootable.
I also like Nick's idea of using a FireWire external if you can find one. I have used FW Target Disk Mode to install the OS on an older Mac that had a dead optical drive.
I still have an official Retail install set for Jag. Your shopping should be focused first on finding this:
The disks with the color "X" are both required installers. The third disk is marked "Developer Tools." This set installs 10.2.3, not 10.2.7, and may be localized based on info on the box's sticker:
Note "RETAIL-USA" on Apple's sticker.
A 10.2.3 installer may work better if you can find one. My set is also on CDs, not DVDs like later install disks, to make them universal. The Beige G3 Minitower for which I bought this set did not come with a DVD drive. The SuperDrive was an option when your A1046 was current.
There are many scammers in the internet's older OS version market. Be very careful in your source selection.
PS: I bought the imaged set at a uni bookstore that was an Authorized Apple reseller. The price sticker is stunning: US$ 129.95! That would have been about 2002.
