I want to clarify: "alongside" works fine IF you ignore the "Use entire partition" and "Use entire disc" options.
Should you choose "Use entire partition" and you have only primary partitions it will erase the whole disc. This of course would be true even with only one primary partition. If you have any pre-existing extended/logical partitions (even just a SWAP) bug #682429 doesn't appear to happen.
I'd still like someone to explain what possible functionality is added by the presence of "Use entire partition/disc" :confused:
Consider that you're a noob and know nothing about partitioning and you've just chosen from three options:
Install alongside other operating systems Erase and use the entire disc Specify partitions manually (advanced)
You don't want to "Erase and use the entire disc" because you want to keep your Windows in tact, and "Specify partitions manually (advanced)" sounds downright scary so you click on "Install alongside other operating systems".
*I should note that the installer will only offer that option if parted recognizes an acceptable arrangement.*
Anyway you next see eight possible options:
Select drive Allocate drive space by dragging divider Offer to use advanced partitioning tool Use entire partition Use entire disc Quit Back Install now
What possible functionality or "value" do the "Use entire" options add? You've already rejected "Erase and use the entire disc" from the previous screen, why offer it again, and this time w/o the Erase and?
And why offer to "Use entire partition"? Throughout my testing it appears that the installer always chooses the largest partition to resize, as it should, so why offer a potentially destructive option at all?
And besides these two bugs negate any possible value added (I contend there is no value is added):
https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/657397
https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/682429
And if you click on "Use entire partition" you then see this:
[ATTACH]177273[/ATTACH]
And then if you click on "Split largest partition" you come back to this:
[ATTACH]177274[/ATTACH]
Does it not appear that the installer is dead set on forcing you to choose one of the "Use entire" options?
*If you choose to ignore those two buttons you should be OK, however.*
Regardless, imagine you have a typical unbranded OEM install of Win XP. Vista, or 7, which will typically leave you with either one or two primary partitions. It could even be a variety of branded PC's as long as no more than three primary partitions exist.
Knowing that "Install alongside" defaults to using the largest available partition, you resize your main Windows partition and create a new partition for Ubuntu, eg(160GB drive):
-5GB Win Utility----55GB Win XP----100GB set aside for Ubuntu
With bug #682429 if you choose "Use entire partition" expecting that only the 100GB partition will be used you're in for a surprise, and not a good one.
Another scenario that makes bug #682429 particularly bad is if someone has Vista or Win7 with a recovery partition. If they were foolish enough to click on "Use entire partition" and found that Windows is now gone, if the installer had in fact only used the main partition they'd still at least have the recovery partition in tact so they could use PhotoRec to recover data to an external source, then use the recovery partition to restore the PC to it's original state, etc.
I still agree with this earlier statement:
If I had my druthers I'd like to just see those options removed and have the "Use largest continuous free space" option restored to the prior screen.
