HDD 160GB SATA

Ubuntu 11.10 （雑誌Ubuntuマガジンの付録）はインストール出来てます。
メディアは 10.04 の環境で brasero で作成しました。
上記マシンには 10.04 をインストールしてあり、これに12.04をインストールしようとCDからインストーラを起動させると、10.04 が起動します。もちろん、M/B の起動設定は CDROM のみの設定になっています。

Ubuntu 11.10 をインストールし、PAEを確認した所、、、PAE　フラグがあったので、PAEが原因ではない事がわかりました。

BIOSのバージョンを最終版にUPしてみましたが、インストーラの起動は出来ませんでした。古いマシンでPAEはサポートされていても私のマシンの様な症状があるので注意が必要みたいです。以上。

ytakagiさん　NG　CPUのレポート有難う御座います。

これ以外のNGだったCPUも教えて頂ければ古いPCの判断が出来るので有難いです。

私のPC環境でもインストールできませんでした。
PC構成は下記の通りです。

M/B  ASUS P8P67(B3)　BIOS 3207(最新です)
BD   LG BH12NS30
CPU Intel corei7 2600
MEM PC3-12800 DDR3 4GBX2
SSD SPCC Solid State DiskB28 32GB

メディアはWin7 64bit環境でImage Burnにて作成しました。
同じ環境で11.10はインストールできましたが、12.04は
メディア起動後、モニターはまっ黒で左上にカーソルが点滅
したままでこれ以上先に進みませんでした。

結局、moriyama_katuさんと同様に
11.10から12.04へアップグレードを実行したらOKでした。
M/BやCPUの組み合わせによってインストールできる
できないがあるのでしょうか。

CPUの仕様が問題になるのはcmov(というのが何なのかは理解していません。すみません。)をサポートしていないi586系CPUや、i486以前のものらしいので、i686以降のものであれば問題無いかと思います。
自分が聞いた、把握している範囲では、AMDのGeode(10.04から12.04にアップグレードしようとしたらアップデートできないといわれました。。)とか、K6, K6-2あたりです。
IntelならPentium II以降なら問題無いかと思いますので、CPU以外のところに原因があるように思います。

ytakagi による投稿:

うちは cpu はcore2duo E8400 ですが、
同じようにインストール出来ません。
たぶん、sandybridge 以降の最新cpu でないと
インストール出来ないのではないでしょうか。

あれこれやってみましたが、結局、ギブアップ。
11.10をクリーンインストールして、直後にアップデートすることで
12.04にしました。

うちでは、それ以外の方法では無理のようです。


まともなインストールを断念し、11.10から12.04へアップデートしたウチのハード情報

投稿＃１４への自己レスです。
外国製の安価な50枚入りパックのCD-Rを使っていての失敗でした。3枚焼いて3枚とも失敗作でした。ひょっとしてCD-Rの品質が悪い所為かとおもい、今日、日本製（1枚150円）を買ってきて試してみたら、Ubuntu12.04が起動できるCD-Rが一発でうまく焼けました。1両日中にポケッタブルHDDへインストールしてみる予定。

8.04、10.04とLTS版を使ってきたので、今回、12.04にしようとubuntu-ja-12.04-desktop-i386.isoをCDに焼いてみたのですが、自動起動しませんでした。真っ黒な画面の左上に、カーソルが点滅するだけです。
いくつかの条件でCD-Rを焼いてみましたが、同じでした。

で、ふと思いついてやってみたことがあって、そちらではインストーラが起動したので報告しておきます。

私はubuntu専用PCとWindows専用PCの２台を使っているのですが、ubuntu専用PC(10.04LTS)ではインストーラは起動しません。
同じCD-Rを、Windows専用PCに入れて起動すると、12.04のインストーラが起動しました。

ということで、このインストーラは、
「WindowsがインストールされているPCに、ubuntuをインストールしてデュアル環境を作る」
ように設定されているのでは、と思うですが、こういうことは考えられるでしょうか。

>インストール出来ないPCのMDIダンプです。エラーとは有りませんか？

訂正です。 DMI ダンプです。

tw_owlさんリプライ有難う御座います。

そうしますと、起動するPCと起動できないPCでは、DMI 情報の中の Memory Array Mapped Address の Partition Width の値が違う程度しか差がないと言う事ですね。

直感として、メモリ配列マップどアドレスだから、インストーラの初期化とかで使われいるような情報であれば、インストール時にコケても可笑しくないような気がしています。

私の起動出来るPCの　Partition Width 32
　　起動出来ないPC　Partition Width　1

ytakagiさんのPC      Partition Width    1
tw_owl さんのPC     Partition Width    0

以上。
